Hi Support:
Patricia's post started me wondering because I have seen unexpected results occasionally.
Using Payables 9.3C I tested both Invoice and Manual Cheque entry. In both cases, I opened batch ## from the Batch List. While the Entry list for that batch was open, I clicked on Print, Listing and Post buttons on the main Batch List window.
Invoices:
Both the Listing and Post buttons correctly said that "Batch ## is already open". Neither function proceeded further and operation seemed unaffected.
Manual Cheques:
Both the Listing and Post buttons correctly said that "Batch ## is already open". Neither function proceeded further and operation seemed unaffected.
However the Print button was different. It correctly said the batch was open. But none of the buttons from the Entry list screen would work after that. All returned an Access Violation message. It almost seemed as if the data tables were closed.
My tests sound a little different from Patricia's in that I didn't find that a Data Integrity Check was necessary.
