  User Authorizations: Ensure that the user has the necessary authorizations to perform the update. This can be checked with the help of your SAP security team.
  Consult Documentation: Review SAP documentation or notes related to the specific material type and field to understand any restrictions that may apply.
  Use Transaction Codes: If applicable, use transaction codes like MM02 (Change Material) to make the necessary changes, ensuring you are in the correct view and mode.
