The system issues an error message.

How to fix this error?

Check the net weight of material &V2& in the material master. Change,
if possible, the net weight in the business document. If the net weight
can no longer be changed, use the manual follow-up processing of the
characteristic &V1& using the respective maintenance transaction. Note
that manual follow-up processing is only possible for the INTRASTAT and
EXTRASTAT declaration types. You have to update the declaration data
prior to follow-up processing!
