  Check Field Names: Review the field names in the relevant table or structure. Ensure that they do not exceed the maximum length allowed by SAP.
  Rename Fields: If you find any field names that are too long, consider renaming them to shorter, more concise names that comply with SAP's naming conventions.
  Adjust Authorizations: If the error is related to authorizations, ensure that the authorization objects and their field names are correctly defined and do not exceed the length limits.
  Review Custom Code: If the error is triggered by custom code, review the code to ensure that it adheres to SAP's naming conventions and does not use overly long field names.
