Steps to Reproduce

  1. Enable the application for FCM.
  2. Configure an operator for workbaskets with some work in them.
  3. Configure the operator to merge workbaskets.
  4. Use GetNextWork to retrieve a new assignment.


Root Cause



A defect in Pegasystems’ code or rules.  A report definition used in selecting the next work item had a bad condition syntax preventing the possible next work objects from selection.

Resolution



Apply Hfix-28095.
