If you create a production order, the system automatically reserves the required quantities of the components. However, you may need additional parts. For this reason, a distinction is made between different goods issues for withdrawals of components for an order:
- Planned goods issue (GI):
You enter this GI with reference to the dependent reservation for the order. The system automatically determines 261 (consumption for order from warehouse) as the relevant movement type.
- Unplanned goods issue (GI):
You enter this GI without reference to a reservation as another GI. You choose movement type 261 (consumption for order from warehouse). You must specify the order number as the account assignment.
- Backflush:
With this type of withdrawal, the components are already at the place of production. They are physically consumed in the course of the production process; however, their consumption is not reported until the quantity consumed is known, that is, when completion of the order is confirmed. You do not need to enter a goods movement in inventory management for these components.
When completion of the order is confirmed, you can flag all quantities reserved for the order but not needed as the final issue is effected.
