How I can close my requisitions automatically?

If you use the Desktop Requisition application and did a simple search on it, you may have noticed that you have a lot of useless requests there.

Well, requisitions can be closed in the following ways:                     
1) Direct Issue Materials that have a PO created. (line type = "Material" or "Service")                                               
This requisition will be closed when the PO is closed as well.         

2) Requisitions that have WO associated with them (Line type - other than "Material" or "Service")
These requisitions will be closed when the WO is closed as well        

3) You can create a new escalation or workflow to make the status change. You may change the requisition status to CLOSE or CANCEL
Regardless of what you choose to do this (WF or escalation), you must create a status change action for both.
