Concepts Tasks Settings Work Order Requisitions APM automatically creates requisitions for the materials or services that need to be purchased for a work order. • If the work order does not require approval, APM generates a requisition when the work order is marked as planned. • If the work order requires approval, APM generates a requisition when the work order is approved. A single requisition is created for all of the work order’s purchased requirements. A requisition line is created for each requirement. (If a work order does not have purchased requirements, no requisition is generated.)
