Read the following scenario:
Sales order is created with delivery plant A. No stock on plant A.
Purchase requisition is created from plant B to plant A (intra-company flow or stock transfer order).
Problem is that the purchase requisition needs a price. It is not logical because intra-company flow (stock transfer in same company flow) is like a stock transfer without purchasing. So in my mind, I don't have to maintain price.
Also if I use ME27 to create manually STO between both plants, price is not asked.
Other question is: is it possible to create directly a purchase order when sales order creation (and not purchase requisition, newt convert into PO)?
