BW Reporting on BPC Dimension Property

Hi all

I have a problem when trying to use the 'Select filter value' in my BEx query which is built onto of the Transient Query sourcing our BPC model.

As we did not want our BEx reports displaying long hierarchies, we have added a set of dimension properties populated with values to be reported in BPC.  This means that can essentially 'flatten' our hierarchy in the BEx reports.

This is working OK at the moment during initial testing.

However, for whatever reason, it appears that we cannot 'Select filter value' on these dimension properties

See below, the filter selection for BW_FC_GROUP only gives us '#' but if we add it as a drill down in the report you see all of the values.

Has anyone got any ideas how I can get it to be selectable from the list ?

Thanks

Ian
