Hi Tech Experts ,
I am working on Cognos Reports , facing report slowness on mutlidimensional cross tab reports which using FM Model (DMR ) .
if i suppress null rows and columns takes minutes to give values with out suppression report is faster ,but i need to cleanse the data before showing to customer .
Instead of using suppression, try changing your data item to something like:
filter([Cube].[Dim].[Hier].[Level],[Measure] is not null)
