• What is the cause and solution for SAP error message C0890 - Characteristics added to char. list because message category was changed ?

  Review Changes: Check the changes made to the characteristics, especially the message category. Ensure that the changes are intentional and necessary.
  Update Characteristic List: If characteristics have been added to the list due to the change, review the characteristic list to ensure it reflects the current requirements.
  Revert Changes: If the change in message category was not intended, consider reverting it to its previous state.

  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling classification and characteristics.
