The GL Codes sub-section of the system is where you can set the general ledger (GL) or nominal ledger (NL) codes that can be assigned against the line items of an order. The GL code is assigned on the invoice when matching an invoice against the purchase order.
From the GL codes sub-section you can view, edit or add new GL codes. Depending on your permissions you may not see all of these options.
