The Direct Delivery button should be available on the returned sales order.

A sales legal entity in Germany, selling to German customers, is receiving stock via direct deliveries from either LE Poland or the LE in the Netherlands.

When RMA's are created, the stock needs to go back to the Warehouse the goods came from. After creating the RMA, the Returned Sales order screen is used to create the direct delivery purchase return orders for all the lines. This needs to be done per line now, when the vendor (LE Poland or LE the Netherlands) is unequal to the default vendor on the item. Prone to error..

It would become easier if, alike this can be used on the sales order, the button create Direct Delivery can be used on the Returned orders. Then the correct vendor can be more easily set on the lines and the direct delivery purchase return order can be made for the full return order in 1 action.
