Whenyou perform sales in the retail POS, for items configured with different"Product type" and CFOP codes, executing the "Print fiscalZ" function (at the end of the day) failswith the following error message:
"The changes to the database were committedsuccessfully, but an error occurred while updating the object context. TheObjectContext might be in an inconsistent state. Inner exception message: AcceptChangescannot continue because the object’s key values conflict with another object inthe ObjectStateManager. Make sure that the key values are unique before callingAcceptChanges."
The fix can resolve current issue.
