  Adjust Configuration: If the mismatch is due to configuration, adjust the settings in the relevant SAP modules (e.g., controlling, financial accounting) to ensure that the field lengths match.
  Review Master Data: Check the master data for the sender and receiver objects to ensure they are correctly defined and consistent.
  Custom Code Review: If there is custom code involved, review it to ensure that it correctly handles the data types and lengths.
  Testing: After making changes, perform thorough testing to ensure that the error is resolved and that data is processed correctly.
