Deleting a Change Request that was created thru P5310

Hello,

User created a change order relating back to a Job that was created thru Job costing module.

Change Request was created with no issues, but user went back into header of change order and manually changed the status code (BSTC) to a "3" - Proceed in Scope.

Status field is greyed out and we need to either 1) delete  Change Order  or 2) change the status field (BSTC) back to a "P" for pending.

We tried deleting the change order, but these are the errors we are encountering:

                1) Delete invalid - Change details exist

                 and

                 2) Delete invalid - Account balance exists.

Any suggestions on how to fix?
