Executing a Warehouse Reorganization 
Use
You use this function to optimize the access paths within your warehouse. Here, Extended Warehouse Management (EWM) uses a warehouse order to reorganize your stock. Since EWM uses a warehouse request for the warehouse reorganization, you can plan your reorganization and start it in a wave.
Features
EWM executes a temporary storage bin determination, which makes no reservation. EWM uses the results of the storage bin determination within the wave determination.
