So from your PRD/QA servers you can restore this JEXC easily..
Can you do one thing--what was the total number of Access sequences before and After upgrade???(T682 total number of entries)why system is unable to miss only one???
By the way which condition type uses this JEXC while creation of Excise invoice??
you can see this previous total number from QA/PRD--if there is no changes among the servers.
alternatively you can see SCU0--Cross system view...
Hope it may helps.
