Business Objects FAQS

3. What is Conformed Dimension?

Ans: One dimension used for two fact tables is called conformed dimension.

Galaxy Scheme is having more than one Star schema like

Conformed dimensions can be used to analyze facts from two or more Data

marts.

Ex: If we have two data marts one are Sales and second are Shipping

Facts. Those two facts are using Customer dimension is called conformed

dimension.

Conformed facts: In addition we need conformed dimension, you needconformed facts.

4. What is Data mart?

Ans: Logical Subset of complete data warehousing.

5. What is Surrogate key?

Ans: Surrogate key is a substitution for the natural primary key. Surrogate keys

are keys that are maintained in the Data warehousing instead of keys taken from

source data systems.

Use of Surrogate key is

Data tables in various source systems may be use diff keys for the same

entity.

Surrogate keys are maintained in the Dimension tables, not in fact tables.

Suppose if we have one field Price in source table. That source Price will

change every year. But in Target we put different keys for maintain the

History of data so we can use Surrogate keys.

6. Data Staging Area?

Ans: Its nothing but Data Presentation area. Relational database into which data is

extracted from data source, transformed into common format, checked for

consistency and made ready for loading into the data-warehousing database.

Fact table contain foreign keys represents. Other tables one to many.

2/40

7. What is Aggregation?

Ans: Aggregation is process of calculating summary data from detail sources. The

use of Aggregation table used to improve query performance.

8. What is shared dimension?

Ans: Shared dimension is like normal dimension but its shared and used by all

components and data marts in the data ware housing.

9. Data cleaning tasks

Combine multiple name fields into one field.

Breaking down date fields into separate year, month, and day field.

Common codes like false to 0, True to 1.

Common formats using like Telephone numbers, Credit rating codes to

common like good poor. Creating and applying Surrogate keys for dimension tables.

10. What are the advantage and disadvantage of Snowflake schema?

Advantages ` Disadvantages

The size of the dimension table is

reduced and data value redundancy is

avoid because parent-child hierarchies

are no longer collapsed.

Increasing the tables may affect query

performance because of necessary

addition joins.

11. What is Denormalization?

Ans: According to ware housing concept Denormalization is process to improve the

performance of the warehouse.

Denormalization nothing but allowing redundancy of data in our dimension

tables. If this happen with our data performance will increase and query time is

comparative.

12. What is schema?

Ans. Schema is a graphical representation of database structure. Schema containstables and joins.

14. What is Factless Fact?

Ans: If fact table does not contain any measures. Then its called factless fact table.

8/4/2019 BO's FAQ's1

3/40

30. Normalization means one table split into different tables. So when you use

Snowflake schema.

That means finding hidden patterns and relationship in data.

31. What are the differences between Star and Snowflake schema?

Ans:

Star Snowflake schema

Denormalized Normalized

In Star central fact table surrounded by

De-normalized dimensions.

Contain central fact table and

Normalized Dimensions.

It contain Redundancy It does not contain Redundancy

It will take large space It will take less space

Maintenance is not required Maintenance is required

Star schema performance is very high Performance is very low because

numbers of tables are increase so joinswill be increase. Performance is slow.

33. What is Data Mining?

Ans: Data mining is process of extracting the knowledge hidden from large volumes

of raw data.

36. What is Junk dimension?

Ans: Junk dimension is a convenent grouping of flags and indicators.

117. What is difference between Data warehousing and Data mart?

Ans: Data mart is a logical subset of Data warehousing. That means it is specific

subject information it contains.

The Data warehousing is a collection of Data marts.

That means Data warehousing is used an enterprise level and Marts are used

on Division/Department level.

123. What is advantages and disadvantages of the snowflake schema?

Ans: The snowflake schema is an extension of the star schema.The main advantage of snowflake schema is the Disk storage space. It takes

less space.

The disadvantage is the additional maintenance effort needed due to increase

number of lookup tables and query performance will decrease.

in Schema.

20. What is Charm Trap?

Ans: A Charm Trap is a type of join path between three tables when Many to

One join converge a single table.

21. What is FanTrap?

Ans: Fantrap is a type of join path between three tables when a One to Many join

links a table, which is in turn linked by another One to Many, join.

22. Compatible and Incompatible objects?

Ans: Suppose in Universe one Inventory Fact table is there. So Inventory fact table

has vendor dimension then the Vendor dimension is not require for Inventory so its

called Incompatible fact table.

23. Generally in Data warehousing prepare B-Tree indexes and then Bitmap

indexes.

24. What type of Universe is there in BO?

Ans: Linked Universes or Master Universe or Detail Universes are there.

26. What is Security Domain in BO?

Ans: Repository for storing security information.

32. How will you give Row level security in BO?

Ans: Two ways are there first one is Creating database and assign permissions.

In supervisor we have one options command Restricting Dialog Box.

34. Difference between BO 5.0 and 6.0?

hand sql options in BO.

8/4/2019 BO's FAQ's1

6/40

Shared:- Allows access to data for all BO and WI users.

Shared connections are use full in a Universe testing environment.

Secured: Centralized and Control access the data. Its stored in Repository.

It is useful we can update at any time. You must connect a repository using the BOrepository key file. The default name is BOMAIN key.

38. When will you go for Alias and Context?

Ans: When a join is a self join then it will go to alias and remain joining then go for

context.

When in Designer we have more than one fact table than you can go for

context. Otherwise if it is normal snowflake schema then you will go to alias.

An important thing is you dont create alias for fact table.

39. What are the Universe Parameters?

@Script:- It is useful for VBA macro. You can specify VBA macro each time

query that includes objects.

@Scipt (variable name,type,script_name);

44. What is Loop? When it will occur?

Ans: Loop is set of joins that defines a closed path through a set of tables in schema.

Loops Occur when joins form multiple paths between lookup tables.

45. Why Loops come in Designer but not in Database?

Ans: Generally in DB each path is included individually in a query. So its not

return duplicate rows.

But in Designer needs to allow queries that included more than one path.

46. When you will go for Alias and Context?

Ans:

Only one lookup table Alias

A lookup table that receives only one end

of join

Alias

Two or more Facts Context

55. How to set table width and height?

And: Go to file page setup in that we can set the table width and height.56. How to set dynamic report size (not append one report to bellow report)?

Ans: Using bellow report definition select below report go to format table and goto appearance and go to horizontal or vertical width set to 1. Then its not overlap.

57. Suppose in your document has 3 or 4 reports if one query is running very slow

how to find?

Ans: Using Data Manager Tool. In Data manager tool its display all queries in leftpane and select that one and see go to Definition tab it will display all information in

below.

Ans:

You can see how many queries are running in current report.

You can modify the name of result.

You can test the same query in different Universes.

You can link the one variable to another variable.

You can see the query report and time it will take that particular query.

59. How to display the values in list of values like Jan, feb, march, apr..?

Ans: In month object double click and open edit properties tab and select edit

button query panel will display select sql button and write query for that like

Oracle: select distinct month_name from table_name order by month_number.

Sql server: select A.month_name from (select distinct cast (month_number as

numeric) as Mon, mon_name from date_dim) A order by month.

60. How to display in cross tab report like Jan, Feb, and Mar?

Ans: The scope of analysis dialog box allows you to select dimension to include your

drill scope of further analysis.

Suppose in query panel if you dont want to any hierarchy you can use scope

of analysis.

72. What is Disadvantages of Context?

Ans: The disadvantage of Context is it will expose the data base structure to users.When you refresh it will ask what Context you want. So that is exposing the

structure of DB.

73. Is it possible to hide the information in BO?

domain. In Document and Universe we have Test and Develop, Production

Document and Universe domains are there. Just we can connect and use and sign

out the domain.

81. Some situations Rankings are not support. What are the situations?

Ans: Generally Rankings are put on the Dimensions.

If in the Dimension has Previous () function [ex: previous (year)]. Its will not

work.

82. Why it is not possible to export the Shared connection Universe?

Ans: Shared and Personal connections Universes are not possible to export in to

Repository because these metadata is stored locally. But secured connection

86. How many ways to link the universe?

Ans: 3 ways are there to link the universes

Kernel approach

Master approach

Component approach

Kernel approach:- In kernel approach core universe has common components and

derived universe have some new components. In derived universe have core

universe components as well as those specific components.

Derived universe=core universe + own specific components.

Master approach: In master approach the derived universe are always a sub set of

the master universe. That means there is no new component added specific.

Component approach: The component approach involves merging of one or more

universes into one universe.

Derived universe=universe1+universe2

87. How you will deploy the universe in different domain?

Ans: Generally deployment domain and production domains are there and

development domain is used for developer and production domain is used for

Testing.

8/4/2019 BO's FAQ's1

14/40

You can use export option in designer file --> export. You can select which

domain you want export and rename the universe back universes. Identification is

stored in locally so two same names are not allowed. So you can change the universe

name in different domain in same repository.

are East, 10 users are South like that in report 4 blocks are there like East, South,North, West. So first 10 North people only see the North Block. And send 10 East

people only see the East block remaining are not visible. Like a row level security.

110. What is difference between for each and for all?

Ans: For each operator tells the BO to add Dimensions on default context.

8/4/2019 BO's FAQ's1

17/40

Ex: Suppose your report have only Year and Sales revenue. You want add

Quarter but dont change the object (only year and sales revenue) just you can use

for each.

For all operation tells the BO to remove the Dimension from the default

calculation context.

111. What is Dimension object, Detail and Measure object?

Ans: In Designer an object has qualifications that are Dimension, Measure and

Detail object.

Dimension object: It is an object that is character data such as Name, City

and Dates.

Drill down hierarchies contains only Dimension objects.

` Measure: A Measure object that retrieves the numeric on dimension objects.

This value will change depend on the Dimension data.

Detail: A Detail object always associates with Dimension object. It isadditional information of Dimension object.

112. What is difference between Condition and Filter?

Ans: A condition is applied to Query to limits the data retrieved from database.

Whereas.

The filters are applied to the data in the document to hide the information

and display only information that you want to appear.

113. What are the requirements to link the Universes?

Ans: To link the Universes we have following conditions

Kernel and active (Derived) universe are created from same RDBMS.

Master detail report the section will display individual blocks will different.

122. Suppose one report will send to user to user then that report where it stores in

repository?

Ans: It will store in Document Domain only.

124. What is difference between @variable and @prompt?

Ans: The main difference between @variable and @prompt its not display the

LOVs. so we cant restrict the user.

125. How the BO supports the user define functions?

Ans: in .PRM file you can insert the function name and parameters return values.

126. Fact table types?

Ans: Fact table contain facts and foreign keys to Dimension tables. The primary key

of fact table is usually a composit key is made up of all foreign key.

Types of facts

Additive

Semi additive

Non additive

Types of fact tables

Cumulative

Snapshot

127. What is slowly changing dimension?

Ans: The SCD is problem of Data warehousing we can solve using 3 types

New record replaces the original record. No trace of the old record

exists.

A new record is added in to the customer dimension table. So its

maintain History but large space required and performance is low.

New field add to table. So its keep some part of history. Disadvantage

is it does not keep all historical.

128. MOLAP, ROLAP, HOLAP

Ans: Online analytical process

MOLAP: In MOLAP data is stored in multidimensional cube. The storage is not in

the relational data base. But in proprietary fonts.

8/4/2019 BO's FAQ's1

20/40

Advantages: Excellent performance. MOLAP cubes are built for fast data retrieval

and is optimal for slicing and dicing operations.

Can perform complex calculations. All calculation s have been generated

when the cube is created.

Disadvantages: Limited in the amount of data it can handle.

129. What is a user object?

Ans: Suppose if any object is not included in Designer that object is created in

report level that object you can use in query panel.

130. What are the drawbacks of user objects?

Ans: The drawback of user objects are stored in locally. So you can manually copy

and paste in another system.

131. What types of users are there in Supervisor?

units that can be handled independently. Portioning data can be done by in different

ways.

By Date, By line of business, by geography, by organizational unit, by all of

the above.

Generally in DWH portioning date By date is popular.

140. What are fact and dimension tables?

Ans: In DWH tables can be classified into two ways

151. How to restrict the data using prompt?

Ans: By using the prompt we can restrict the user means the user has to select the

value from list of values. So according to the values the report could be generated.

152. What the problems you faced while creating reports? Which is problematic

report explain?

Ans: Some times I cant understand the logic. Once I understand the logic I wont

get any problem.

153. How can you specify hierarchies in report?

Ans: By using the scope of analysis tool in query panel we can specify hierarchies.

154. What is Awarenes Index? Why we use?

155. How can you get data from two data providers?

Ans:

156. Why do you get three select statements?

Ans: While creating the object we use Case statements. So in the case statement we

define select parameters depend upon number of statements we get number of

selects.

157. We created one template? Can we use this template in another system?

158. What is Complex Report?

159. In report I want to display only Negative results like -10000 not +10000. how to

do?

Ans: Using the filter in filter we have to specify the condition as less than zero.

161. What is materialized view?

Ans: Materialized view is a static view. It contains data. To create materialized view

we should have sufficient privileges.

162. Suppose Universe1 is there from Universe1 one report is generated. Universe2

is there this universe is exact copy of Universe1. Unfortunately universe1 is deleted

so is the report work generated from universe1?

Ans: Yes the report can work even though the universe1 deleted because the base

tables of the both universes are same so it can work properly.

163. What is KPI and Metric? How these appear in report?

164. Difference between Condition and Filter? And which is fast?

Ans: Condition which applies to query to limit the data retrieval. And Filter which

can hide the data means it will show what ever the data we want.

Condition every time interact with the database and check the data whether it is

exist or not. So it will be slow. Filter will be fast because it will not go for database

every time because data will be stored in microcube. It will fetch data from

microcube.

165. What are complex calculations?

166. Suppose in designer two tables are there but they are not joined. So when you

run check integrity what message you get?

Ans: Table_name not linked to anything. Suppose if we have number of tables then

the number table names and not linked to anything.

167. What is derived table?

168. How to restrict the number of rows in report?

Ans: If users want to limit the number of rows returned by a calculation, they can

use only existing objects as a condition in a query.

169. What are the features included in WebI 6.0?

Ans: WebI version 6.0 narrows the functionality gap between two platforms,

providing improved graphics, a more intuitive interface, simpler workflow, multitab

and multiblock reports, and report variables and formulas. Web based reports

never been so rich! Where as users previously had to sacrifice functionality for thin-

client computing, WebI version 6.0 removes many of those barriers and offers even

more enhancements.

170. Can we pull the views into structure pane?

Ans: Yes we can pull the views into structure pane like the tables into the structure

pane.

175. What is Calculation Context?

Ans. A powerful feature of Business Objects is that you can reuse the same

calculation in different parts of the reports. Business Objects recalculate according

to the context in which you place the calculation: a grand total at the top of the

report, section total for each section. You can also define the calculation contextusing specific syntax, which tells Business Objects which dimension objects you

want to exclude or include in the calculation context.

176. What is Chart Legend?

Ans. A Chart Legend is essential here to explain what the different lines and

columns on the chart present.

177. How many items can I choose from a LOV picklist?

The default is 99. You can increase the limit to 256 using the MAX_INLIST_VALUESparameter. In v5.1, this parameter is set in the driver.prm file. To use it, you must enter it inthe [RDBMS] section under the (GENERAL) subsection. If you do not enter this parameter, thedefault value is 99. In v6.5, the parameter is not set in the driver.prm file. Use the File,Parameters, Parameter dialog within Designer. The setting is stored with the .unv file, and istherefore universe specific.

178.How can I implement row level security?

How to Implement Row-Level Security

First -- what is Row-Level Security? When you want to specify which rows of dataeach userid is permitted to retrieve from the database, based on some column of

data, or combination of columns of data -- that is row-level security.

Row-level security can be implemented in BusinessObjects in several possible ways.

If you have a tech support login, you can look at some of the techniques and thepros and cons in Steve Krandel's 2002 International User Conference presentation

Using Designer to Implement Row-Level Security.

Here are some of the ways possible:

1.) By letting the database do it. This is usually the most secure, although for logistic

reasons, many sites do not find it feasible. To make this work, individual logins haveto be set up in the database for each user, and those logins need to correlate to the

BusinessObjects login and password. A possible way is to have a security table that

is joined to the fact table(s) -- via a view -- and use the view in BusinessObjects. Forthis to work, the universe connection will need to specify "Use BusinessObjectsusername and password". (This has sometimes been called "Advanced Login

Strategy" in the past.)

2.) In BusinessObjects Supervisor -- for a given group or user, select the universe.Go to the Rows tab of Universe Properties. Click the Add button, and select the

table to be protected. Enter the appropriate WHERE clause to be imposed. However,only 256 characters of a WHERE clause can be entered in this panel, which many

8/4/2019 BO's FAQ's1

27/40

folks find very restrictive.

3.) A workaround to this is to define the WHERE clause in a special object inDesigner, and impose that object in Supervisor, using @WHERE(special_object) for

the WHERE clause.

4.) You can impose the security restrictions in Designer, by using self-joins and amaintained lookup table. You might end up with self-joins along the lines of:

Code:

DataTable.Region in ( Select Region From SecurityLookup Where User =

@BOUSER)

179.How do I create cascading or nested prompts?

Let's create a Series of Cascading Prompts for the Island Resort Marketing Universe. We'll

simply work our way through the Resort class for a quick example. All of the prompts will be

fairly similar, and I am going under the assumption that everyone has some Designer

Experience.

Let's start at the Highest Level that we'd need a prompt for. That would be the Resort itself,

since we need to know what Resorts we're interested in.

* Edit the List of Values for the Resort object.

* Check the Automatic Refresh Before Use option.

* Click Edit.

* Bring Country into the Conditions and set it to: in list Prompt('What Country are

you interested in?')

* Click Save and Close

* Click Apply and edit the next LOV object.

Edit the Service Line and set up the same Prompt on Resort as: in list Prompt('WhatResorts are you interested in?')Again... Save and Close, ensuring that the Automatic Refresh Before Use checkbox isselected then Edit the next.

Service will have: Service Line in Prompt('What Service Lines are you interested in?')with the Automatic Refresh...

--------Save this Universe and let's generate a report.--------

Generate a report that pulls in the Country, Service Line and Revenue. Set a prompt onService Line and apply a prompt as a condition asking: 'What Service Lines are we

tracking?'

Refresh this report.

For the Service Line, click on Values.... A new Prompt should appear, asking about theServices. Again... click the Values button, and so on... and so forth.

Once you've answered the questions, you only need to hit the Values button when you needto backtrack to another level.

180. isolated join?

Select View > List Mode.

3. Decide which context you wish to include this join in.

4. Double click on the context name to bring up the context editor window.

5. Find and select this join from the list provided.

6. Close the window.

Further checks of the integrity should show no divergences in structure

181. How do you create an @Prompt for an aggregate aware object?

Define two aggregate aware object in two different classes:

- Object1 in Class 1

Select clause:

@Aggregate_Aware(Agg_4.Year,Agg3.Year,agg2.Year,Agg_1.Year,format((Sales.invoice_date,'YYY

Y'))

- Object2 in Class 2

Select clause:

@Select(Class1\Object1)

Where clause:

@Select(Class1\Object1) = @Prompt('Question ?','A','Class1\Object1',,)

Referencing the Object1 in the where clause of the Object2 will permit to use the prompt function.

Next you just need to hide the Object1 for the final users.

181. What is the character limitation for the names of objects, classes, and

universes?

The limit is 35 characters for creating classes, objects, and universe names.

There is no character limitation for their descriptions (contextual help).

8/4/2019 BO's FAQ's1

29/40

182. Within an object definition in the universe, can you use set operations like union or

intersect?

Set operations, like union and intersect, cannot be used within an object definition in the

universe.

183. How can you add a join to a pre-existing context?

Here are the steps to follow:

1. Open your universe in Designer.

2. Go to View > List Mode.

3. Double-click on the pre-existing context.

4. Highlight the join you wish to add.

5. Click OK

The join will then be added to the context.

184. How long can an object description be?

You are limited to a number of characters when entering the description of the object in

the Designer module. You can enter approximately 30000 characters for a descriptionwhich corresponds to 96 records of 240 characters.

The descriptions are stored in the column OBJ_DATAVALUE VARCHAR2(240) of the

table UNV_OBJECT_DATA.

If the description does not fit in one record, then several records will be created for thesame object

Note: The Select and Where statements of an object are stored in the

OBJ_DATAVALUE field as well. The description is where the field OBJ_DATATYPE

= 'H'.

185. In Designer, how can you refresh all the List Of Values (LOV) of the objects in a universe atthe same time?

In order to refresh all the LOVs of a universe do the following:

In Designer 6.5 and Designer XI, click Tools>List of Values >Refresh button.

186. Q. How does BusinessObjects decide whether to recommend Contexts over Aliases

or vice versa?

A. The detection algorithms used by BO is as follows:

The product will firstly attempt to propose Aliases for tables which cause a loop in thedatabase schema. These are typically found on the outer parts of the schema, and often

referred to as leaf nodes.

Secondly, the product will attempt to resolve loops caused by a centralized FACT table(a

table containing two or more MANY relationships as exits and not containing any ONE

relationships as exits) by proposing one or more Contexts.

b

You have a condition like the following:

Table.Column IN ( decode ( @Prompt('Select name?','A',{'a1', 'a2', 'b'},multi,free))

This will display a prompt with a LOV button in which you can select each single value.

In Designer, you want to set an LOV that has a set of grouped values to choose from likethe following:

Choose "a1" & "a2", or "b", or all values "%" ?

Resolution

*****CONFIGURATION******

BusinessObjects version 5.1.x

Oracle 8i and 9i

**********RESOLUTION******

Create your condition in the object Where clause or in a Predefined Condition in your

universe using a syntax like the following:

Table.Column IN

( decode ( @Prompt('Select name?','A',{'a1 & a2','b','%'},multi,free), 'a1 & a2', 'a1' ),

decode ( @Prompt('Select name?','A',{'a1 & a2','b','%'},multi,free), 'a1 & a2', 'a2' ),

decode ( @Prompt('Select name?','A',{'a1 & a2','b','%'},multi,free), 'b', 'b' )

)

or '%' = @Prompt('Select name?','A',{'a1 & a2','b','%'},multi,free)

This condition will generate a prompt with an LOV button that will display the followinglist:

{ a1 & a2 , b , % }

For example, if you select the value "a1 & a2", then the condition that you apply will be:

Table.Column IN { a1 , a2 }

8/4/2019 BO's FAQ's1

32/40

Note: The @prompt() must be replicated exactly the same way for each of the possible

values in the "decode" function.

189. How can you implement contexts and shortcut joins in youruniverse?

Symptom

You have a universe that has a number of contexts and shortcut joins. In BusinessObjects,

you are selecting objects from different context routes. They should then produce a dialogue

box for the different contexts, however the box does not appear.

Cause

Shortcut joins are not included in the contexts.

Resolution


BusinessObjects version 5.x

**********RESOLUTION******

Make sure that you have an entry in the appropriate parameters (.PRM) file for your

database that includes the following parameter:

GLOBAL_SHORTCUTS=Y

190. How do I generate a correlated subquery in the universe?

A condition such as "maximum date" can be complicated to implement in

BusinessObjects. The following example explains how to embed this complex definitionin a predefined condition in the universe. This will allow you to drag-and-drop this

predefined condition in the Query Panel to obtain the desired result

1. Open the Designer.

2. Select Insert > Condition.

3. Enter a name for your condition, such as "Last reservation date."

4. After modifying it to suit your universe, copy and paste the following statement in the

WHERE clause window:

8/4/2019 BO's FAQ's1

33/40

RESERVATION.RES_DATE = ANY

(

SELECT

max( T1.RES_DATE )

FROM

RESERVATION T1

WHERE

T1.CUST_ID = RESERVATION.CUST_ID

)

191. How do you create a List of Values based on the value of a previous

prompt?


1. Create two objects.

2. In the "Select" of the first object, add the name of the column that will be deduced from the

first prompt (the subgroup). For example:

table.city

And in the "Where," add the following:

Table.region = @Prompt('Type a region','A',,mono,free)

In this example, the "Select" string has "city" (the subgroup) and the "Where" string has "region"

(the group).

3. In the "Select" string for the second object, put the fields you want displayed after the "group-

subgroup" drill. For example:

Table.budget, table.city

4. In the "Where" clause, put the following:

8/4/2019 BO's FAQ's1

34/40

table.city=@Prompt('Select name?','A','class_first_object\first_object',multi,free)

Note: The second object can use a table other than the table used in the first object.

192. What does array fetch size mean?

The array fetch size setting allows the universe designer to select the maximum number of rows

that is authorized during the fetching procedure. This controls the packet size on the network. If

the designer specifies 20 and when performing the query it is planned to retrieve 100 rows, the

module executes five ("5") fetches to retrieve the data. If you retrieve binary long-object (BLOB)

objects, the value 1 should be entered as the array fetch size.

Note: Some data sources will not allow modifying the fetch size; all rows will be returned in a

single fetch in this case

193. How can you change the default sorting for the List ofValues (LOV) of an object?

Symptom

The default setting for the sort on a List of Values (LOV) is to sort in ascending order.

You want them to be sorted in descending order.

194. How can you create an object with a constant value ?

Symptom

You want to create an object that will return the same value independently of thedatabase (for example, "1"). This is not a BusinessObjects feature, but it can be done.

Resolution



**********RESOLUTION******


1. Create your object in Designer and give it a name (for example, "ONE").

2. The select part of the object should contain the constant (for example, "1").

3. Do not associate any tables to your object.

Your object will not parse, but it will run fine as long as you associate it with other

objects in your queries.

195. How does BusinessObjects decide whether to recommendContexts or Aliases?

195. What is the difference between a personal, a shared, and asecured connection?

Resolution



**********RESOLUTION******

A SECURED connection is used to centralize and control access to sensitive or critical data. It is

the safest type of connection.

A SHARED connection is used to access shared resources.

A PERSONAL connection is specific to one user on one computer.

*********WARNING***********

This resolution involves making modifications to your database. This is not an operationsupported under normal procedures of BusinessObjects, therefore we recommend thatthis operation only be performed under the direction of your database administrator.

Create a backup of the database before making any changes.

**********RESOLUTION******


1. On an 'Employee' table in your database, create a column called 'Emp_Age' containingtwo-digit numeric values.

2. Create an additional table called 'Age_range' containing three columns called 'Low',

'High', and 'Text'.

3. Open Designer and add this table to your universe structure.

4. Create a complex join between the 'Emp_Age' column on the 'Employee' table to thenew table 'Age_range'.

Note: The join for this would be 'Employee.Emp_Age' between 'Age_range.Low' and

'Age_range.High'

5. Create an object named "Age Range" based on your column called 'Text' to allow youto group employees into age ranges.

universe?

Symptom

8/4/2019 BO's FAQ's1

38/40

You insert a table into a universe and experience poor performance. The operation takes a

significant amount of time.

Cause

Designer may be extracting joins, detecting cardinalities, or creating default classes andobjects from the tables. It analyzes these prior to inserting the table which increases the

amount of time dramatically.

Resolution



**********RESOLUTION******


1. Start Designer and open your universe.

2. Go to Tools > Options > "Database" tab.

3. Near the middle of the tab you will see options enabled by default. Uncheck the

following options:

- Extract joins with tables

- Detect cardinalities

- Create default classes and objects from tables

199. Designer will not detect more than 500 loops?

Symptom

You attempt to detect the loops in your universe and the process stops at 500.

For example, in Designer, open or create a universe with many tables and joins, creatingat least 500 loops.

Verify that the Auto Join Detection option is set to "on".

Go to Tools > Detect Loops.

**********RESOLUTION******

200. Why are the contexts defined in the core universe not present in the linked

universe ?

Symptom

Contexts defined in the core universe are not present in the linked universe.

Cause

For integrity reasons, it is not possible to transmit the contexts (or hierarchies) defined in the core

universe to the linked universe.

When you link a universe, you inherit the tables from the core universe. After this, you can still

make changes on the linked universe which are not replicated in the core universe. Therefore, you

can destroy a context without being aware of it and thus create problems which can be difficult to

solve on large universes.
