Once an order has been released and allocated in the NCAS, a pick list is generated for the order. The pick list shows the allocated quantity for each item to be picked. Once the items have been picked, the picking activity must be posted in the NCAS.

If a pick is posted in the NCAS with no exceptions, the following item balances decrease by the quantity picked as soon as the pick is posted:

• On-hand quantity

Note: As the on-hand quantity at the warehouse decreases by the quantity picked, the on-hand quantity in the staging area increases by the quantity picked. In other words, the inventory is moved from the online storage area of the warehouse to the online staging area.
 

• Allocated quantity
• Released requirements quantity
• Total requirements quantity

For example, if nine chocolate bars are allocated to the snack bar’s order and nine are picked, the on-hand quantity, allocated quantity, released requirements quantity and total requirements quantity at the food supply warehouse decrease by nine as soon as the pick is posted in the NCAS. At this time, the items have moved from the online storage area to the online staging area.

 

	On-hand  quantity	Total  Requirements  Quantity	Released  Requirements  Quantity	Allocated  Quantity	Available  Quantity	Available-to-  Release  Quantity
Beginning  Balance	15	0	0	0	15	15
Order  Entered into  the NCAS		+9
Order Released and Allocated			+9	+9	-9	-9
Pick Posted with no Exceptions	-9	-9	-9	-9
New  Balance	6	0	0	0	6	6

A partial pick also works in the same way as a pick without an exception. Since partial picks are incomplete, the NCAS assumes that the remaining quantity of the pick will be posted at a later time. Therefore, all the item balances are adjusted only by the quantity physically picked and posted to the NCAS.
