I have a problem with filter and crosstab,
when I use a filter in on crosstab, appear an error:
"This query contains set aggregation. Detail of summary filters should not be applied"
and not le me use a filter,
why?
Is this ReportNet or Cognos 8?
Sounds a lot to me like Cognos 8 - with the report written using a dimensional package. What filter do you wish to apply? Could it be done with a slicer?
