Background: Set AP Paid Status
Use the AP Paid Status Close (NPX) program to set the status of a PO line to "paid" which indicates that the line has been closed for AP purposes. If you need to reset the status to "unpaid" use AP Paid Status Open (NPXO). See Road Map for work flow.
If AP interfaced to purchasing? in System Options Maintenance (XM) Accounts Payable Options is selected, the system updates the paid status when receiver lines are invoiced. However, you can also enter invoices (in AP Invoice Entry) without specifying a receiver line. Although you can process a payment for the invoice, the PO line remains "not paid" (i.e., open for AP purposes). AP Status Close enables you to set the status of such PO lines to paid. AP Status Open enables you reset the status to "unpaid" should it be necessary.
If the Inventory interfaced to GL? system option is selected (set in System Options Maintenance - Inventory Control Options), you will also have to set GL Journal Options for the AP Clear Register (journal source GJ5). When a PO line is set to paid, the AP accrual account is debited (using VRJ (PO Receipt Register) posting parameters); the organization and account on the PO line is credited. If a line is re-opened, postings are reversed: AP accrual is credited and the GL account on the PO line is debited.
