I have a storage location S001 which is inventory managed and we already has stock available at the Inventory level. Storage Location S001 is previously non WMS managed and now the same S001 is re configured as WMS. Please help me with the steps I need to do in order to bring the stock under WMS. Is there a mass Transaction that can be used to do the Warehouse movements? Also, before we make S001 as WMS do we need to do the IM stock transfer?
You should have removed all the stock from Sloc S001 prior to attaching the warehouse and then put it back into Sloc S001 after the warehouse had been attached, this would then automatically flow through to the warehouse.
If you do it now, you will get a neg qty in WM.
If possible, you should remove the warehouse, remove the stock from S001, reassign the warehouse then reload the stock into S001.
