53.Movements involving the Inventory Management system use storage areas that are defined as storage types in the Warehouse Management system and as storage locations in the IM system. The goods receipt for a purchase order is posted first in Inventory Management and the goods are then brought into the warehouse via a storage area, the goods receipt area. What are these storage areas called?
- Interim storage area
The interim storage area plays a special role and can be generally be recognized at first glance in the standard system by their key ( which starts with a 9).

- Special movement indicator
56.Sometimes a customer cancels an order at the last minute or wants to postpone the delivery until a much later time than planned. If the goods have already been picked and taken to the goods issue area, they have to be returned to storage. What is the transaction available and what are its functions?
