Not showing any values in Filter Window after executing report on Portal or RSRT

Hi All,

I am facing an issue after executing report in Portal or rsrt . Whenever I am trying to Filter on any of the Fields displayed  in the report the Filter Window opens but only displays # - Not Assigned as the value there but the report displays other values too and those should also display in that window.

The Report is based on a Composite Provider and Composite Provider is based on 4 Analytical Indexes with 1 in Union and 3 in Join Condition.

Please give you suggestions to resolve this Issue.

Thanks,

Vimarsh
