  Missing required fields or attributes.
  Data that exceeds length restrictions.
  
  
  
  Configuration Issues: There may be misconfigurations in the data model or the replication settings that lead to format discrepancies.

  Solution:
  
  
  Check Data Format: Review the data being sent to ensure it adheres to the expected format for the object and subscriber. Validate data types, lengths, and required fields.

  Verify that the mappings between source and target systems are correctly defined.
  
  
  
  Data Validation: Implement data validation checks before attempting to write data. This can help catch format issues early.
  
  
  Update or Synchronize Versions: Ensure that both the source and target systems are using compatible versions of the data model or schema.
  
  
  Error Logs: Check the SAP application logs (transaction SLG1) for more detailed error messages that can provide additional context about the issue.
