SAP BI is an enterprise-wide comprehensive decision support system (DSS) for the analytical needs of an enterprise

BI can also support some degree of operational reporting

The SAP BI tool set has many traditional presentation tools and options for companies to leverage. We are not looking at BOBJ tools at this stage.

The SAP NetWeaver BI Traditional Toolset

Visual Composer 7.0 is for SAP BI Development, 7.1 and higher is for the Composite Environment (CE). We now have version 7.3

There are different SDN forums and blogs for each - This can be confusing!

There are Two 'versions' of Visual Composer (VC)

6

Visual Composer for Dashboards

A Visual Composer is a tool to visualize the data.

It is a browser-based modeling and design tool for rapid application development & prototyping in a code-free development environment.

7

Visual Composer for Complex Dashboards

Modeling of BI applications using Visual Composer allows users to create analytical content. It integrates with infoproviders, views, BEx web applications, Xelsisus, PDF, APIs, and access to OLAP and relational data sources

8

Visual Composer is Easy to Learn

Visual Composer is a power user tool that is simple to learn for someone with a little bit of technical background i.e.

controllers, report writers and analysts.

No coding is required to create good-looking Web-based cockpits

Visual Composer Some Graphic Examples

For SAP BW - It All Starts with a Query

The BEx Query Designer

The query is the core method for accessing BI data. You can use existing queries in your SAP NetWeaver Visual Composer models

SAP NetWeaver Visual Composer Data Methods

• Can integrate data from multiple data sources, including SAP and non-SAP systems, into one model

• Different options available for data access include: BI Extension Kit Remote Function Call (RFC) Web services

• BI Extension Kit allows access to the following DataSources SAP NetWeaver BW 7.0 and 7.3 SAP NetWeaver BI 2004

(SAP BW 3.5 Support Package 14) JDBC XMLA

Visual Composer Data Providers

• You can use BI queries and views as Data Providers for SAP NetWeaver Visual Composer models

• You also can use BI query functionalities for exceptions and variables along with SAP NetWeaver Visual Composer models

• SAP NetWeaver Visual Composer allows access to BI history, favorites, and roles

13

SAP NetWeaver Visual Composer 7.0 & 7.3 - Portal Publishing

SAP NetWeaver Visual Composer 7.0 design-time deploys models directly as iViews to the Portal Content Catalog. You can then use the iViews in portal pages, roles, etc.

In VC 7.3 you can either use portal modeling as a tool, or publish to the Generic Portal Application Layer (GPAL). Any iViews, pages and portal objects are created using the GPAL which exposes applications and portlets deployed to AS Java.

14

SAP NetWeaver Visual Composer 7.0 Using BOBJ Xcelsius

SAP NetWeaver Visual Composer 7.01 (or 7.02) SP5 or higher allows you to use existing Xcelsius UI controls and use them inside Visual Composer.

You can also use any Flex component made by Adobe Flex Builder (Flex 2 SDK).

You can download flash objects & 'how-to' on sdn.sap.com (by Sap's Amir Mimran)

You can download a

CE trial version on

the SAP Community

Network

Downloading and Getting Started — The Trial Version

However, to put it into production you must work with your SAP account executive for a license. It is normally

not covered by a general SAP license.

Remember that this is a power user task, so providing the group with some formal training (4-6 hrs) would be

beneficial. Also, teach them your naming conventions.

The first task is to create an overall model to store all your pages and

iViews

The name cannot have blanks or

special characters

You can organize your model in

standard folder structures

Creating a Model

If you don’t have Adobe SVG installed, you must go

to their Web site and download it. It is a small

file and it is free.

The models are actually graphics rendered with

Adobe SVG (vector graphics)

The SAP NetWeaver Visual Composer Add-Ons

First you must make sure that your SAP

NetWeaver VC environment is set up with connection back to your SAP environment(s).

The Work Environment — Getting Connected

You can also work with your technical team to set up connections to other non-SAP environments.

This tool bar allows you to zoom, access layers, insert grid lines for layout, and move objects.

We can add items and see then from

the highest level, or you can “drill down”

on each item and configure them

individually

Navigation is provided as a

toolbar and you can also zoom in on

each item

The SAP NetWeaver Visual Composer Configure Toolbar

SAP NetWeaver Visual Composer

has many tools that power users can

play with

The fastest way to proficiency is to try the many features

Very few things can break, and the undo

button is always available

The magnifying glass is helpful when the model is very complex and zooming in and out is cumbersome.

The Magnifying Glass

When you are developing very complex models, it is

very helpful to add annotations (comments) to document your work.

Consider proposing standards within your company (i.e., dates, initials, and what needs to be documented).

The Annotation Tool

Very large SAP NetWeaver Visual

Composer cockpits can be hard to read

The Browse feature allows you to see the

cockpit in a tree format that makes it easier to

navigate

Graphical model displays can get hard to read once very complex dashboards are created.

Getting an Overview Over Complex Models

The best way to create cockpits is to prototype it first, then ask for feedback. Since this is a discovery-oriented process, it is not a best

practice to use functional specifications to create Web cockpits. Rapid Application Development (RAD) is the preferred methodology.

Plan on spending serious time with users working on

layout and Web page organization

P.S.! You can use the SAP delivered

calendar for display, or for users to

interact with your data set

Development Methodology

SAP NetWeaver Visual Composer uses the

standard GUI Modeling Language (GML).

If you are familiar with this language, you can see the

code page under the Source tab.

The Back-End GML Code

We will build a dashboard based on 2 queries called country and customer view, and present this with tables and graphs as well as navigational links between them (passing variables between the queries)

Our Target Dashboard

You can look at existing queries developed by others.

In this example we will create a Web Cockpit based on two SAP NetWeaver BI queries.

More advanced developers can also call Business Application Programming

Interfaces (BAPIs) that are delivered with SAP NetWeaver BI to build complex

applications.

Step 1 — Find the Data You Want to Model

Step 2 — Selecting the Queries and Defining a Starting Point

1.After the query is selected, the metadata is transferred to the model.

2.We select one query as the starting point and can require users to use a prompt (in

this example we will leave this blank).

1.We add a table view and select the fields we want from the query.

2.We give the table view a meaningful business name.

Step 3 — Adding a Table View Based on Query Data

Step 4 – Adding a Chart view based on Query data

1.We add a chart view based on the query data.2. We decide to make it a column chart.

3. The fields that we want to graph are selected.4. We add animation to the column chart.

1. We select the fields we want to graph as different data series (columns).

2. We give each column a meaningful business name (this is what the users will see).

Step 5 — Defining Graph and Assigning Meaningful Names

We can suppress the sum rows from the query, so that the graphs are more meaningful and the tables are less cluttered.

Step 6 — Suppressing Zero Values from the Query

1.When a user selects a row in the country table, we want to show all the customers in that

country and their sales.

2.We link the output from the country table view to the customer query and map the country-key

value between the two objects.

Step 7 — Adding Navigation: Linking Tables to Other Queries

1. We also want to give the users the option to click on a country in the graph and see all

the customer’s sales.

2. Again, we link the output from the country graph to the customer query and map the country-key value between the objects.

Step 8 — Adding Navigation: Linking Graphs to Other Queries

Previously we added a table and a graph of country sales. Now we want to add similar views for

customer sales.1. First we add a table view.

2. We select the fields to be displayed from the query.

3. We give the table a meaningful name.

Step 9 — Adding a Table View for Customer Sales Data

Now we add a pie chart.

1. First we add a graph view.

2. We select the pie chart type and the fields to be graphed.

3. We give the field a meaningful business name.

Step 9 — Adding a Table View for Customer Sales Data (cont.)

Again, we suppress the sum rows from the query, so that the graphs are more meaningful and the tables are less cluttered.

Step 10 — Suppressing Zero Values from the Query

In the layout section we arrange the objects and resize them so that they look good. We also compile the model and can now view it in the Portal

Step 11 — Layout and Compiling of Dashboard

All country sales are displayed based on the first query

The Result: The Web Cockpit in SAP NetWeaver Portal

By clicking on the country in either of the top views, the

bottom views display sales for those customers

The Result: Navigation Between the Graphs

Demo – A complete cockpit from scratch

External Web services such as email, stock quotes, news services, and weather

maps can also be integrated into your SAP NetWeaver Visual Composer cockpit.

External Web Services

Each Web service may require different input, so you have to spend some time trying out what works for your site and how to

format it.

External Data Providers — Web Services

49



Performance Tips: BIA and Summary Cubes

1) If your cockpits are at a higher level such as weekly or monthly, consider the use of summary cubes to reduce the data accessed (also take a look at building aggregates).

2) For high volume or high number of users, you should seriously consider the BW Accelerator Solution. This compresses the data and stores the data in memory (no disk access when queries are run).

This is “hyper fast”…

51

Making Cockpits Fast — Using the Cache as a Data Provider

• It is very beneficial to use the cache as the method for data service retrieval

• This makes the cockpits faster by relying on previously accessed data stored in-memory You can also use

broadcasting to cache as a method to pre-populate the cache as well

Since a cockpit may have many different DataSources (queries), it can take quite some time to execute them if the memory cache is not

used consistently

Leverage the OLAP and the MDX cache to speed up the initial loading of the web page. Consider using jump-to and drill down

links to more detailed information.

Performance Tips: Using jump-to and drill down query links

• If you pre-run the underlying queries using BEx Broadcaster, and cache the results, you can make the VC cockpits open much faster.

• You can then also use Web Application Designer to provide links to the underlying queries for more detailed information.

• When user click the link, the query will not be run again (already in cache).

Upgrade Options to v 7.3

There are no automated upgrade paths from NetWeaver VC 7.0 to NetWeaver VC 7.1 or 7.2. However, you can upgrade to version 7.3

When upgrading to VC 7.3, you have two options: Design time migration Run time migrationRun time migration is when the already deployed VC 7.0 content is migrated to a new NetWeaver 7.3 machine. The design time refers to the migration of the actual VC models from 7.0 to 7.3.

Jarrod Williams from SAP has written a great migration handbook,

that is available on the sap developer network

55

What is new in version 7.3- Components and deploying

Models can be stored locally or in a source code system. With the transition to Dynpro, we store the models in the NWDI Design-Time Repository (DTR). This provide version controls that was unavailable in 7.0

In Visual Composer 7.0, we used iViews, in 7.3 we can use components

In 7.3 you can also have many models open at the same time (different tabs) and you can use Integrated Planning (IP) queries in your model.

such as ‘composite views’ or ‘service component’ for advanced data services.

Models created in version 7.0 use adobe Flex, while models in 7.3 use Web Dynpro (Java) and can be rendered in Web Dynpro HTML and Web Dynpro Flex.

The design and layout access is now placed on the bottom toolbar

56

What is new in version 7.3 – More UI Controls

You also have access to control each User Interface (UI) component. Actually, you are required to add services and then assign UI controls (in 7.0 this is ‘pre-assigned’ by object selection), if you don’t do this, you simply won’t see anything.

This gives much better control over the UI components (like BusinessObjects Xcelsius)

Image source: J. Williams, SAP AG, 2011

You can also open your 7.3 models in SAP NW Developer

Studio for more custom development

57



In the Tools Options section, you can control items such as auto save, display levels, formats,

highlights, and more.

These preferences are stored for each user and can be

personalized.

Who gets to use the SAP Visual Composer?

There is a temptation for the IT community of wanting to keep the Visual Composer tool under their domain – That is a mistake

- Spend time teaching Super Users VC

7 Key Points to Take Home

• SAP NetWeaver Visual Composer is a tool that is easy to learn

• The tool is intended for power users – Not primarily IT

• SAP NetWeaver Visual Composer is not going away

• You should provide individual training to each of the power users

• Spend serious time performance tuning the back-end queries and data stores

• Plan for SAP NetWeaver BW Accelerator if you have many users of the SAP NetWeaver Visual Composer models

• Seek advise of best practices and plan on integrating data across systems, Web services, and other non-SAP sources
