Combine "hide empty rows" with EPM pane member selection

Dear all,

We build an input screen that include that include multiple dimensions, each of them having many members but only predefined combinations of dimensions members should be available for budgeting.  For that purpose:

• We created an input screen that include only the possible value
• We also entered dummy values (0,01) for each possible combination of dimension members in order to use the standard functionality "hide zero and/or empty rows".
• We activate the above functionality (hide zero and/or empty rows)

This work fine until we try narrowing the number of rows by removing some selected dimension member via the EPM pane, when refreshing the data we get the error message about "too many tuples" as if BPC first tried to generate all possible combinations of dimensions members before narrowing the selection to the "non zero or empty" rows.

Any idea on how to combine these two options and on a more general way how to handle predefined combinations of dimensions members

Thanks and regards

Thomas
