You can add Custom dimensions as needed. There is no limit to the number of Custom dimensions that you can add, but adding many additional dimensions may affect performance.
You specify Custom dimension information as part of the Application Profile.
You can also use the Modify Application method to add Custom dimensions. See the Modifying Applications section in the Oracle Hyperion Financial Management Administrator's Guide.
Example: If you add Product as an additional Custom dimension, set ProductTopMember to SystemMembers.
Do not set a CustomTopMember for the ActiveRegion account.
Example: If you add Product as an additional Custom dimension, set EnableProductAggr to Y for all Tax and Book Accounts.
Example: If you add Product as an additional Custom dimension with Products as a member, set ProductTopMember for the CurrentTaxExpense account to Products. Repeat this step for each additional Custom Dimension added.
Example: Products should have the Inactive UD property pointing to one of the members: Inactive: 0010.
Update the application to include the new Custom dimensions. See Updating Applications with Additional Custom Dimensions.
