I wanted to throw it up here in case anyone has experienced this. A client states that their 'next automatic' PO number has been incrementing by large amounts on its own (i.e. Last 'automatic' PO number used was '0037498', but PO Options is now showing the next automatic number to be '4302643'). They are configured to use the SO number for SO-generated POs, but I don't believe that should affect the automatic numbering (and their SO numbers are currently only up to the '100000's).
Any comments would be appreciated!
