Internal Versus Purchased

The system uses the Internal or Purchased Resource Source Flag (RESRC_​SRC_​FLG) value set on the Resource Type in determining how it should process the Activity Resource Requirement (ARR). If set to Internal, the resource is added to the estimate. If set to Purchased, the system automatically generates a purchase request requisition to be processed to a purchase order for Issue to a vendor as soon as the ARR or Activity becomes activated.
