I am receiving the following:
"QuickBooks returned an error when adding/modifying a accPurchaseOrder
record. The error was: There was an error adding, modifying or deleting
FFAF-1238106148 because it is already in use. QuickBooks error message:
The transaction could not be locked. It is in use by another user..."
I received this error after manually changing the PO Number (RefNumber) on the Purchase Order Tab. Method sync'ed with QB and generated a po number 1012. Then I added "-2091" at the end: PO Number 1012-2091.
Also, I do not have this file open in QB.
