Inventory Lot Quantity Issuing Restrictions
Some manufacturing environments allow WIP inventory quantities to be driven negative by overissuing of material; others do not. WIP inventory is the amount of WIP material that resides at an operation. If these types of restrictions apply in your manufacturing environment, sort them by routing. Then sort any restrictions within each routing by operation.
Example: You have WIP lot 5A with 50 items at operation 30 of routing 101. At operation 40, you issue WIP lot 5A with 100 items. This issue would result in an overissue of 50 items, giving you a negative WIP QOH of 50 items at operation 30. You note that for routing 101, overissuing of WIP is allowed.
Use the information you collect regarding issuing restrictions to create records in Routing Registration Maintenance (3.22.13.1) that prevent or allow WIP lot overissuing based on the routing or routing operation.
