Explode Sales BOM in repair order (RA)

Hi,

we have a scenario in wich we need a repair sales order (RA), for which we want to receive all the components of a product (exploding the sales BOM as returns in the "repair" tab of the item), and deliver the finished product repaired. Is there a way to explode a sales BOM in repair order?

As an alternative solution, we could use a standard BOM explosion, but we need to change the sales order item in stock assignment of the production order. Do you know a BADI or an exit to realize it?

Thank you.
