Purchase requisition remains in INPROCRESS, even after the final approver approves.

Hi Guru;s
Kindly advice as Purchase requisition remains in INPROCRESS, even after the final approver approves.

Actual Scenario:

For Purchase Requisitions, AME is being used.

The final approver in the hierarchy is on leave and vacantion rule is active.

Now when the final approver(i.e the approver who is approving on behalf final approver) approves, the Purchase Requisition status remains INPROCESS.

Thanks,
Nath.
