How to create and maintain Warehouse Requests outbound?
Warehouse requests on the outbound side is made when the order document is released. Watch the process in this video.
This is what happens in the video
So when releasing the order, we create the request then we do all the activities and when we are done and we post the warehouse shipment, the sales order would also be posted and that will delete the warehouse request.
This means that in all that period if you have deleted the warehouse pick to start all over, or you delete the warehouse shipment because you want to bundle several sales orders together in a new shipment or for any other reason, the request will still exist if you reopen the sales order changing the sales order and you release it again, it will actually delete the request and then create a new one when you release it again.
So in this way, the request is maintaining the relation between the sales order and the warehouse activities.
