You specify in Manufacturing Constants (P3009) whether the commitment for the work center quantity is hard (committed to a specific location) or soft (committed to the item's primary location).
If the item is not attached to a work center and if you have set the manufacturing order entry program's processing options to check the staging location for item availability, the system does not create a pick request if a sufficient quantity of the item exists in the staging location to complete the work order.
Warehouse personnel can do one pick for the same items, increasing the efficiency of the warehouse.
As you enter a work order, you identify the parts to include in the work order parts list.
You create a pick request in response to a sales order (or a parts list, for manufacturing systems).
You use pick requests to generate suggestions for locations from which to pick items. You can find locations containing the items that you must ship and then create suggestions to pick from those locations.
You can set up manufacturing system so that the creation of a parts list triggers the creation of a pick request for the necessary parts.
Some items that in the manufacturing process might be out of stock temporarily, so they are not eligible for picking.
