MDX in Analysis Services: Create a Cube-Based Hierarchical Picklist - Page 3July 26, 2004 Procedure 1. Right-click the new Exp_Finance cube 2. Select Edit ... from the context menu that appears, as depicted in Illustration 5.
The Cube Editor opens. 3. Right-click the Calculated Members folder within Cube Editor. 4. Select New Calculated Member ... from the context menu that appears, as depicted in Illustration 6.
The Calculated Member Builder opens. 5. Type the following into the Member name box: RS_PX_StoreGeogPLName_Hier While the name of the calculated member can obviously be anything useful in the environment in which we are creating it, I typically use a name similar to the above, in order to make it apparent, both inside Analysis Services and in the reporting application (Reporting Services in this article), that the calculated member exists for use in the reporting ("RS") application, that it has been created to support picklists ("PX"), and that this particular calculated member exists to generate a picklist display name ("PLName") in our reports for the various levels of the Store dimension. 6. Type the following MDX into the Value Expression section of the Calculated Member Builder: Space([Store].Currentmember.Level.Ordinal * 6) + [Store].CurrentMember.Name The MDX expression above returns, via our calculated member, a display name that we will use to generate the picklists that the information consumers see, as part of being prompted, each time they attempt to generate a report in which we insert the picklist to support a parameter. An explanation of the components of the above expression appears in Table 1.
Table 1: Expression Components Summary NOTE: For an explanation of the .CurrentMember function, see my article MDX Essentials: MDX Member Functions: "Relative" Member Functions in the MDX Essentials series at Database Journal. The Calculated Member Builder appears with our input as depicted in Illustration 7.
