System Response

The system has established that the product <ZG>(Invoiced quantity -

set in the Customizing system for quantity variance.
When the invoice is posted, the system blocks the invoice for payment
with the blocking reason "Quantity variance".

How to fix this error?

Check what you have entered and make any necessary corrections. If you
post the document in spite of the variance, the system will carry out
the posting and the associated account movements. However, the document
will contain a block indicator which will not allow it to be paid.
