I have gone through number of links and discussion regarding Stock Transfer Order. I am still left with some doubts.
Say if there is 10 different plants and each plant make stock transfer to each one with SD Delivery and Billing (for shipping). In this case, we cannot make the assignment of Customer&Vendor.
1. Is it possible to route these kind of scenarios through PO route?
2. If 313/315 is used - what about the SD Delivery and Billing.
This discussion and the document provided by Jurgen is helpful:
