Thank you! The multi-select is there. When I select multiple entities the data disapears from the report. Do I need to add a business rule that tells the report to add values together as multiple entities are selected?
Chances are that your report is simply placing that Parameter in the Cube View POV. You cannot have multiple members there, so it breaks.
You will probably have to restructure the Cube View, at a minimum placing Entities on rows or columns, maybe adding some calculated rows for totals (look up CVC and CVR functions). No Business Rule required.
A more complex alternative is to use a Pivot Grid instead of a CV, but you will need to create a Data Adapter to feed it, and that is a bit more complicated (not necessarily requiring rules, but you'll need to know your way around Data Adapters).
