QBWin.log: LVL_ERROR--Error: Verify item history target quantity on order mismatch error

A mismatch between your item history and certain items on orders can occur if the ItemHistUpdateEngine fails to update the item information. The message A data problem prevents QuickBooks from continuing appears while backing up your file and your QBWin.log shows the following error after verifying data:
