In September, we completed the assembly of a product and sent ship it to the customer. Unfortunately, we did not replace one of the components in the Bill of Materials (BOM) as per the customer's request. Now, the customer is requesting the correct part to be installed.
The challenge is that we have already shipped multiple quantities to other customers with serial number (SN) traceability enabled as part of the assembly order. I need guidance on how to retrieve the unit that was sold, replace the necessary part, and maintain proper record-keeping.
In simpler terms, is there a way to disassemble the assembly order and replace the part, or should I consider making a journal entry to rectify this situation?
