Hi Bruce,

Unfortunately, there is little in Barb's post to help us track down any specific issue. What actually happened when the batch "refused to retrieve"? Was there an error message? What did it say? What were people doing in each module at the same time? While we have been working hard in the 9.0 versions to relax th multi-user record locking, I don't believe we made any intentional changes in the AP release in this regard. By any chance, did you make a backup of the data before attempting the post? Was the problem repeatable?

When a batch has errors, the transactions that are not in error are posted, and the error transaction are written to the error batch. It sounds like every transaction failed to post. Is that the case? What was the specific error you had during posting in AP? What about in your test data?

I think we'll need more details to try and track this down.
