After you release a work order, you can print its picklist. The picklist lists the component requirements and the sites, locations, lot/serial numbers, and reference numbers for the items to be issued. The system creates detail allocations when an order is released, regardless of whether or not you print a picklist. Detail allocations reserve specific quantities in inventory for a work order.
The picking logic used is determined by settings in Inventory Control.
You can release an order without printing a picklist and routing, but you cannot print a picklist for an order without releasing it.
In a picklist, floor stock appears separately, without site or location. Floor stock should have issue policy set to No for the item-site or item.
For an order with several operations, components can be grouped together on separate picklists by setting their lead time offset (LT Offset) to indicate when they are required with respect to the release date. Define lead time offset in Product Structure Maintenance (13.5) or Formula Maintenance (15.5).
