here the scenarios.
My customer buy an item which I do not have the stock at the moment.
My related company(not with same company code), in this case, a retail store, had the stock.
My customer went to the store to pickup the items.
I do not want the retail store to bill me but I can arrange a STO to transfer the item to my site and from here, I will do a PGI and issue the invoice to my customer.
Beside third party (TAS) and individual sales order item (TAB), can any guru advice if there are other options.
