On click of "Complete" UI action on "Resource Plan" does not delete all the requested and resource allocations for it that are past the completion date.

Flow of deleting the requested and resource allocations
BR Handle state change -> Script Include ResourcePlanStateChangeHandler(Line 34) -> ResourcePlanCompletion(Line 106).
In the script include ResourcePlanStateChangeHandler if the system property "com.snc.resource_management.run_state_changes_async" is set to true then it would not delete.

Update the system property "com.snc.resource_management.run_state_changes_async" to false to resolve the issue

Please note all the requested and resource allocations for the resource plan that are past the completion date will be deleted, but if there are any actual hours logged against an allocation, that allocation record is not deleted
