Duplicate Document Number
I can't export Flex elements to QuickBooks. I get this error:
ERROR CODE:6140, ERROR MESSAGE:Duplicate Document Number Error, ERROR DETAIL:Duplicate Document Number Error : You must specify a different number. This number has already been used. DocNumber=<the number that is a duplicate> is assigned to TxnType=<the type of QuickBooks doc> with TxnId=<the ID of the QuickBooks doc>
Solution
The document number is already in use inside QuickBooks. You must change the existing document in QuickBooks, or use a different number in Flex before re-exporting.
