Error while posting any GR

Question

Dear Experts,
When I tried to post a GR there was Runtime Error         MESSAGE_TYPE_X  :
What happened?
    The current application program detected a situation which really
    should not occur. Therefore, a termination with a short dump was
    triggered on purpose by the key word MESSAGE (type X).
Error analysis
    Short text of error message:
    CO-PA Derivation: Variant configuration characteristic GRADE does not e
    ist
    Long text of error message:
     Diagnosis
         In the settings for characteristic derivation in CO-PA, there is a
         derivation step that uses the variant configuration characteristic
         "GRADE" as a source field.
         This characteristic does not exist.
         Problems usually arise after a transport for which the
         Profitability Analysis settings were transported but those for the
         variant configuration were not.
     System Response
     Procedure
         If the problem occurred after a transport, then you should also
         transport the missing variant configuration settings into this
         system.
         Alternatively, you can also delete the offending derivation step in
         Profitability Analysis.
         To do this, use the transaction Maintain Derivation Strategy
     Procedure for System Administration
