Can not delete or check in segment rules



During a redesign some redundant segments were identified. During a refactor attempt the system stated they are being used by campaign runs with no active campaigns. As a result they could not be deleted or modified and checked into a new ruleset version.

Error Messages

Error occurred during Segment population: Failed to create the table data set for this segment.

Steps to Reproduce

Try to delete old segments that have been used in campaign runs. Try to edit the segment rules in higher ruleset versions.

Root Cause

Pega Marketing does not support Versioning for Segments. The segments could not be deleted because there were a few rules still sitting in the segment class.


Deleting the segment class rules manually should allow you to delete those segments.
