Warehouse personnel create requisitions in the Purchasing module of the NCAS to request the buyer to order the required items from the vendor. These requisitions have no impact on the GL. Commitments for these purchases are made against the Available Funds File (AFF), but commitments are not posted to the GL. In the Inventory module, the on-order quantity for the item is increased by the quantity requisitioned.

For example, your agencys warehouse has just created a requisition for 10 tubes of antiseptic burn ointment. The requisition anticipates that each tube will cost about $1.90 each. This purchase should, therefore, cost $19 (10 tubes multiplied by $1.90). A commitment for $19 is made against the AFF. The commitment is not posted to the GL. In the Inventory module, the on-order quantity for antiseptic burn ointment is increased by 10 tubes.
