Data Sources With Named Sets May Produce Unpredictable Results
If your dimensional data sources include named
sets, which are sets of members or set expressions that are created
for reuse, the data results are unpredictable in Query Studio when
combined with filtering and level nesting.
Additionally, if your data sources include multilevel named sets, the data results are unpredictable in Analysis Studio when aggregated.
We therefore recommend that you avoid exposing named sets or multilevel named sets to Query Studio and Analysis Studio users.
Working with named sets may also cause unpredictable results in Report Studio. For more information, see the IBM® Cognos® Report Studio User Guide.
