When posting in Order Entry the following message is displayed.
Error: Record has been modified by another program.
This error is typical of having an order entry document open, having day end run and complete while that order is still open, then trying to post that order. Day end updates order entry documents in the database while it runs modifying the already open document behind the scenes. The solution to this situation is to run day end at a time when people are not processing in order entry.
