issue is that regardless of when a Job or PO is created it pulls the current Rev, not the rev that was assigned at the time of creation. Example: Material PN "12345" current at Rev 06, but in 2015 when a job was created it was Rev 02, but if you review the 2015 Job the rev will show what is current from the Material File today. Not 02
Need to record the rev level at the time of creation of the Job or PO.
