3 MDX o MDX = MultiDimensional expressions o It is a query language for OLAP databases o It is also a calculation language (syntax similar to spreadsheet formulas) o MDX has been embraced by wide variety of OLAP vendors

4 Basic MDX Query Rows, Columns & Where Statement SELECT { SET 1 } ON COLUMNS, { SET 2 } ON ROWS FROM CUBE WHERE ( TUPLE ) COLUMNS Are defined in CXO-Cockpit by your columns list ROWS Are defined in CXO-Cockpit by your rows list CUBE Is defined in CXO-Cockpit by the source system in system settins WHERE Contains all other dimensions that are not specified in the rows or columns The WHERE is constructed by the POV or fixed dimensions

5 Basic MDX Concepts Member, Set, Tuple & Tuple Set o A Member is one specific Member from 1 specific Dimension and is typically unique. The MDX Syntax for a Member is: [DIMENSION].[HIERARCHY].[MEMBER] o A Set is a group of Members from 1 specific Dimension and is typically unique. The MDX Syntax for a Set is: { [ACC].[ACC].[SALES], [ACC].[ACC].[COGS] } o A Tuple is a group of Members from different Dimensions. The MDX Syntax for a Tuple is: ( [PER].[PER].[JANUARY], [CAT].[CAT].[ACTUAL] ) o A Tuple Set is a group of Tuples with the same dimensional setup. The MDX Syntax for a Tuple Set is: { ( [PER].[PER].[JANUARY], [CAT].[CAT].[ACTUAL] ), ( [PER].[PER].[FEBRUARY], [CAT].[CAT].[FORECAST] ) }

6 Basic MDX Query Example SELECT { ( [PER].[PER].[JANUARY], [CAT].[CAT].[ACTUAL] ), { ( [PER].[PER].[FEBRUARY], [CAT].[CAT].[FORECAST] ) } ON COLUMNS, { [ACC].[ACC].[SALES], [ACC].[ACC].[COGS] } ON ROWS FROM CUBE WHERE ( [YER].[YER].[2016], [ENT].[ENT].[HQ] ) COLUMNS Tuple Set combining two tuples both having PER and CAT as dimensions ROWS Set combining multiple accounts (same dimension) WHERE Tuple with the other dimensions

7 CXO-Cockpit Cube Calculation Structure & Context - Basic calculations o A Cube Calculation always calculates a new Member o Cube Calculations can be applied to Columns (1), Rows (2) or the Where Statement (3) 1 2 3

8 CXO-Cockpit Cube Calculations (1) Structure & Context - Basic calculations A Cube Calculation must always return one of the following results: o A number o A fixed number like 100 o A calculation of other members retuning a number like [Costs] / [Sales] * 100 o A MDX function returning a number like AVG({[Product1], [Product2]}) o A Member of the same Dimension o A reference to another member e.g. YTD: [VIW].[VIW].[YTD_Input] o A MDX function returning a member from the same Dimension like [YER].[YER].[2016].Prevmember o A Tuple containing at least a Member from the same Dimension o For example cube calculation of dimension [CAT] called latest budget: ([CAT].[CAT].[Budget], [VER].[VER].CurrentMember.LastSibling)

9 CXO-Cockpit Cube Calculations (2) General rules o The cube calculation must have a unique name o It must be linked to a dimension (-hierarchy) o In the Calculated member you can use explicit members from other dimension (e.g. the last period of the previous year ) o The static variables available under Maintain Variables can be used in cube calculations o The dynamic can be used in the cube calculations o Other dynamic variables, cannot be used o The order of calculations is important in case of more than 1 calculation in a report

10 CXO-Cockpit Cube Calculation Conditional Statements based on Context o Conditional statements can be made with the CASE WHEN Statement CASE WHEN logical_expression THEN result1 ELSE result2 END CASE WHEN when_expression1 THEN result1 WHEN when_expression2 THEN result2 ELSE result3 END o There are two ways to query the current context o [Dimension].[Hierarchy].CurrentMember Checks the current cell context o <<@@CUR(DIM)>> Checks the POV dimension value

11 CXO-Cockpit Cube Calculation Conditional Statements Examples Entity Cube Calculation for GroupTotal using.currentmember CASE WHEN [YER].[YER].CurrentMember.Name = "2015" THEN [ENT].[ENT].[Geographical] - [ENT].[ENT].[ASIA] ELSE [ENT].[ENT].[Geographical] END Measure Cube Calculation filtering out the current month Sales CASE WHEN [PER].[PER].CurrentMember.Name = "<<@PER_current.Name>>" AND [ACC].[ACC].CurrentMember.Name = Sales" THEN NULL ELSE [MEA].[MEA].[[None]]] END

12 Use of member containing data o In some cases you want to create a cube calc that is applicable to the complete report o To do this pick a dimension of which the detail is not used in the report o This can be an empty dimension with data loaded on the None member o Or can be a dimension of which only the Total member is used in the report o In these cases remember to specify the member on which the data is loaded (in your source system) o Examples: o On the None member of the Measure dimension o On the Total member of the Custom 1 dimension o General rule: A cube calc should at least contain a member of the same dimension the cube calc is created in

13 MDX Functions Most used function groups for cube calcs are: o Member Functions returning a member Like:.CurrentMember,.PrevMember,.AllMembers,.Children,.Properties o Numeric Functions returning a numeric value like: AVG({SET}), MAX({SET}) o Logical Functions returning true or false like: ISEMPTY([Member]), ISLEAF([Member])

14 MDX References o MS Functions library: o MDXpert (good examples):

15 HFM/ SAP BPC vs Essbase vs SAP BW HFM / SAP BPC MS / Tagetik Essbase SAP BW o CASE WHEN [ENT].[ENT].CurrentMember.Name = Asia THEN o CASE WHEN [ENTITY].CurrentMember IS [ENTITY].[Asia] THEN o IIF ( InStr([/CPMB/J6D5IJZ PARENTH1].CurrentMember.Name, Asia ) <> 0,.,..)... OR CASE WHEN IS([ENTITY].CurrentMember, [ENTITY].[Asia]) THEN o CASE WHEN [ENT].[ENT].CurrentMember = 1 THEN o CASE WHEN [ENT].[ENT].CurrentMember = 1 THEN o IIF ( InStr([/CPMB/J6D5IJZ PARENTH1].CurrentMember = 1,.., ) o Null o Missing o Missing o Change order of cube calc by dragging and dropping cube calc o Change order cube calc by changing order number o Change order cube calc by changing order number

16 Specifics Essbase/ SAP Split dimensions o In CXO we often split Essbase/ SAP dimensions o Example: Period dimension into Period and View o In Cube calcs you can specify Period and View members: o The original member can be used o Variables can be used o A specific member of one of the split dimensions can be specified: o In case you want to specify one member of the split dimensions, you need to create variables

17 MDX Troubleshooting Debugging 1. Check the MDX as executed in the CXO-Configurator 2. Execute the Query in Management Studio/ Essbase/ SAP MDXTest to test the MDX

18 Exercises Three important notes: o Create your own Menu item as follows: Intials_Training, e.g. ML_Training Place your reports in your own Menu item o When creating reports during this training, please place your initials at the beginning of a report name. This way we can easily recognize the reports created during this training. E.g.: ML_Profit and Loss o When creating objects, such as cube calcs and lists, please place your initials at the beginning of a object name. E.g.: ML_ROW - Profit and Loss
