We are an AS9120B certified company and are required to maintain traceability on the components we sell. We have been using the Receipt Code as an internal lot code, and this has worked fine. However, when parts are returned to us that will be going back into stock, the RMA receipt creates a new receipt code. There doesn’t seem to be a mechanism to link the RMA receipt back to the original receipt it was shipped from.
How are others maintaining traceability in similar situations?
