• What is the cause and solution for SAP error message RSAR704 - Length of field & was changed from & to & ?

  The SAP error message RSAR704 indicates that there is a mismatch in the length of a field in the data transfer process, specifically when using SAP's Data Transfer Process (DTP) or during data extraction. This error typically occurs when the length of a field in the source system does not match the length defined in the target system or the data model.
  Cause:
  
  Field Length Mismatch: The most common cause of this error is that the length of a field in the source data (e.g., an InfoSource or DataSource) has been changed, and this change is not reflected in the target data model (e.g., InfoObject or DSO).
  Data Model Changes: Changes made to the data model, such as modifying the length of a characteristic or key figure in the target system, can lead to this error if the source data has not been updated accordingly.
  Data Type Changes: If the data type of a field has been changed (e.g., from CHAR to NUMC), it can also lead to this error.
  
  Solution:
  
  Check Field Definitions: Verify the field definitions in both the source and target systems. Ensure that the lengths match for the fields involved in the data transfer.
  Adjust Data Model: If the source field length has been changed, you may need to adjust the target data model to accommodate this change. This may involve modifying the InfoObject or DSO to match the new field length.
  Re-activate DataSource: If changes have been made to the DataSource, re-activate it in the source system to ensure that the changes are recognized.
  Data Transfer Process (DTP) Settings: Review the DTP settings to ensure that they are correctly configured to handle the data being transferred.
  Check for Transport Requests: If changes were made in a development environment, ensure that the transport requests have been properly moved to the production environment.
  Test Data Transfer: After making the necessary adjustments, perform a test data transfer to ensure that the error has been resolved.
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to RSAR704 for any specific patches or updates that may address this issue.
  Data Modeling Guidelines: Review SAP's guidelines on data modeling to ensure that field lengths and types are consistently defined across systems.
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to check the data model and DTP settings.
  Logs and Traces: Analyze logs and traces for more detailed information about the error, which can help in diagnosing the issue.
  
  By following these steps, you should be able to resolve the RSAR704 error and ensure that your data transfer processes function correctly.
