Open the shipped sales order

The parts still returnable are copied across. Lower a quantity, remove a line, add the reason, and set how long the approval is good (30 days to start).
Print it for the customer
Press Print. It carries your logo, the RMA number to write on the package, and what to send with the part.
Receive it, then decide
When the part arrives press Mark received, then Close this RMA with what you decided: credit, replace, repair or reject.
