You mean new job for Part A…
in the material Put
Part A - issue/Consume ( Old Serial Number)
Part B- issue /consume (New serial number)
Reverse Part B- Old Serial Number ( can you reverse material which is not in job??)
Match B (new Sr no ) to A ( New Sr no)
Complete job and Receive Part A ( New Sr no ) in Stock?
The times that I have done it was on an RMA where we would disposition it to a job. So, we had an RMA for part A. We would disposition it to a job when it came in so the job would have part A in it.
We would add a material requirement for part B.
We would issue B (New SN) to the job. At this point you technically have 2 part B in the job. The original B that was in A and the new B.
Unmatch B (Old SN) from A and match B (New SN) to A. Now return the B (Old SN) to stock for an NCR if you want.
Confusing, but it works really well and tracks all of the dollars correctly.
