Ran into a problem creating an accountant’s copy on Quickbooks Pro Desktop 2020. The data file was shared from the server and day to day work was fine.
I didn’t get a screen shot of the error message but it would fail and say that the accountant’s copy was not created. There was a sybase error in the event log on the client machine but referenced the path of the data file on the server.
I added the QBDataServiceUser30 with full control on the path on the server, restarted the QuickBooks Database Service Manager, and it was all working again.
