Zero Suppression in reports (BPC 5.1)

Question

Hello Experts,
In one of our reports we have a performance issue related to MDX formulas used for Zero-Suppression.
Something like:
([Account].Currentmember,[Department].["&$C$4&"],[Actual],["&$H$24&"],[YTD]) <> 0 OR ([Account].Currentmember,[Department].["&$C$4&"],[MP1],["&$I$24&"],[YTD]) <> 0 OR ([Account].Currentmember,[Department].["&$C$4&"],[Actual],["&$F$24&"],[YTD]) <> 0 OR ([Account].Currentmember,[Department].["&$C$4&"],[Actual],["&$D$24&"],[Periodic]) <> 0 OR ([Account].Currentmember,[Department].["&$C$4&"],[MP1],["&$E$24&"],[Periodic]) <> 0 OR ([Account].Currentmember,[Department].["&$C$4&"],[Actual],["&$H$24&"],[Periodic]) <> 0"
With zero-suppression report finishes in ~4 minutes and without suppression - ~30 seconds.
I'd appreciate any ideas on how to improve performance for this report.
Thanks in advance,
Akim

If you have multiple ranges in EVDRE statements, all expanded ranges will flow through the same formatting section or selection range.  So, many customers build a sytle guide driven design, that uses properties, colum markers, row markers, esentially several layers of format commmands that result in the desired formats.  All formatting flows from TOP to BOTTOM, so each defined format may overwrite the next, should you have defined similar markers and/or formats for the cell.
The other option is to break the ranges into multiple EVDRE statements, which each has there own set of formatting instructions.  Just remember that EVDRE's are executed in a sequence from A1, to the end of the column, B1 to end of column, etc.
Hope this helps.
