  Custom Development: If custom fields or tables have been created with names that exceed the allowed length, this error can occur.
  
  Solution:
  
  Check Field Names: Review the field names in the table mentioned in the error message. Ensure that they comply with SAP's naming conventions and length restrictions (typically, field names should not exceed 30 characters).
  Rename Fields: If any field names are too long, consider renaming them to shorter, compliant names. This may involve updating the database schema and any related code or configurations.
  Adjust Data Migration Mapping: If this error occurs during data migration, adjust the mapping to ensure that field names are shortened or transformed appropriately before the migration process.
  Consult Documentation: Refer to SAP documentation for specific guidelines on field naming conventions and limitations.
  Testing: After making changes, perform thorough testing to ensure that the changes do not affect the functionality of the application or data integrity.
  
  Related Information:
  
  SAP Naming Conventions: Familiarize yourself with SAP's naming conventions for fields, tables, and other objects to avoid similar issues in the future.
