Issue
Unable to create an outage via major workbench if we have a data policy exception on cmdb_ci_outage table.
Cause
The "Begin date mandatory on all outage records" data policy is causing the issue.
This is expected behavior as the 'Create' action on the Outages card first creates a 'cmdb_ci_outage' record and then opens the record in the iFrame
Since, we have a data policy on the 'cmdb_ci_outage' table it errors out on creation itself and therefore does not open any modal.
Resolution
Please implement the same logic using ui policy so that it would not error out on backend insertion of record.
