Calculating Values Using Range Functions

• Mathematical

• @SUMRANGE

• @AVGRANGE

• @MAXRANGE

• @MINRANGE

• Exceptions

• @CURRMBRRANGE

• @PRIOR

• Financial

• @SLN

• @IRR

• @COMPOUND

Calculating Values Using @SUMRANGE

Sums values of a specified member across a range

Example:

Q1_SALES =

@SUMRANGE(SALES, JAN : MAR) ;

Result:

Q1_SALES = 600

Sales:

Jan: 100

Feb: 200

Mar: 300

Calculating Values Using @AVGRANGE

Averages values of a specified member across a range

Example:

Q1_AVGSALES =

@AVGRANGE(SKIPMISSING,SALES, JAN : MAR) ;

Result:

Q1_AVGSALES = 200

Sales:

Jan: 100

Feb: #MI

Mar: 300

Calculating Values Using @MINRANGE and @MAXRANGE

Supplies minimum or maximum value of a member across a range

Examples:

Q1_MIN =

@MINRANGE(SALES, JAN : MAR) ;

Q1_MAX=

@MAXRANGE(SALES, JAN : MAR) ;

Results:

Q1_MIN = 100 Q1_MAX = 300

Sales:

Jan: 100

Feb: 200

Mar: 300

Calculating Values Using @CURRMBRRANGE

• Returns a member list based on the relative position of the member being calculated

• Can be used only with range functions

Example: Six_Month_Total =

@SUMRANGE (Sales,

@CURRMBRRANGE(Year, LEV, 0,-5 , 0))

/"Average Inventory” ;

Calculating Values Using @PRIOR

Returns the value from the previous or the nth previous member in a range of members

By default uses the lowest level of a dimension tagged as Time

Example:

Inventory = @PRIOR(End_Inv) ;

Result: Jan Feb Mar Apr May Jun

Inventory 1100 1100 1200 1000 1300 1300

End_Inv 1100 1200 1000 1300 1300

Exercise 4-1:Calculating Values Using

Range Functions

Obtaining Values Using Relationship Functions

• @PARENTVAL

• @ANCESTVAL

• @MDPARENTVAL

Obtaining Values Using @PARENTVAL

Returns the immediate parent value of a specified member combination

Example:

PRODUCT_MIX=SALES % @PARENTVAL(PRODUCT,SALES);

Result:

PRODUCT_MIX is calculated for New York

PRODUCT_MIX = 50%Given EAST = 100,000, New York = 50,000,

Obtaining Values Using @ANCESTVAL

Returns a higher level value of a specified member combination based on specified generation or level

Example:PRODUCT_MIX=SALES % (@ANCESTVAL(PRODUCT,2,SALES));

Result: PRODUCT_MIX = 10 %

Given Colas (Gen 2) = 100,000, Diet Cola (Gen 3) = 50,000, Kool Kola (Gen 4) = 10,000

Obtaining Values Using @MDANCESTVAL

• A higher level value of a specified member combination, based on position specified across multiple dimensions

• References any dimension and any generations

• Marketing = (Sales / @MDANCESTVAL(2, Market, 2, Product, 2, Sales))

* @MDANCESTVAL(2, Market, 2, Product, 2, Marketing);

Exercise 4-2:Obtaining Values Using Relationship Functions

FIX(New_York,Camera,Actual,Mar) LOOP(30) Commission = Profit * .15; Profit=Margin-Total_Expenses-Commission; ENDLOOPENDFIX

Controlling Execution Using Loop…Endloop

Use the LOOP...ENDLOOP command to specify the number of times to iterate a group of calculations.

Syntax:

Explaining Simultaneous Equations

• Unknown values exist on either side of the equal sign.

• A = B * .15, where A and B are unknown.

• B = y - A, where y is data and A and B are unknown.
