Table Filtering Creo 4.0

Creo 4.0-  In drawings the Table; Repeat Region; Filters; By Item has stopped working.  The error at the bottom of the screen states:

"You may not perform this action due to symbol dgm.run.cond.from.pin.signal."

Checked all the parameters in table.

The same table was working fine in Creo 3.0, Recently migrated to latest version.
