Issue
Problem with Manual Approvals in Workflow
Release
KP5
Cause
The out of the box "Before Query" business rule named "Approval Query" has skipped during the upgrade
Resolution
There is a "Before Query" business rule named "Approval Query" that has the skipped the upgrade. This business rule has been turned to Active "false" in Kingston version. Since it has skipped the upgrade, the business rule was still "active" in the prod instance and it altered some of the queries to the "Approval" table and therefore the issue occurred.
Revert the business rule to the OOB version resolved the issue.
