Help needed with Drill Through‏

[sag4cognos]

Hello All,
I have two reports.
The Source report - built on Audit Package - returns the list of emp id's who have run a certain package during a certain time period.

The Target report - built on HR Package - provides the contact details of emp ids.. I have set up a drill through from Source to Target, and the entire set up runs fine - for any single emp id selected.

My question is I need to extract the contact details of ALL the employees who had ran reports against a specific package. I have included an in_Range filter in the Target report, enabled multi select in drill through condition, but I am not able to pass multiple data items ( from the same column ) to the Target report..

Any ideas or suggestions?   ???
Thanks, Sagar
