• What is the cause and solution for SAP error message RSAR703 - Data type of field & was changed from & to & ?

  The SAP error message RSAR703 indicates that there is a mismatch in the data type of a field in the context of data extraction or data transfer processes, particularly when dealing with SAP BW (Business Warehouse) or SAP Data Services. This error typically arises when the data type of a field in the source system does not match the expected data type in the target system or in the data model.
  Cause:
  
  Data Type Change: The most common cause of this error is that the data type of a field in the source system has been changed (e.g., from CHAR to NUMC or from INT to DEC) after the data model was created in the target system.
  Inconsistent Metadata: There may be inconsistencies in the metadata definitions between the source and target systems, leading to mismatches.
  Data Source Changes: Changes in the underlying data source (like a database table or view) that affect the data types of fields being extracted.
  
  Solution:
  
  Check Data Source: Verify the data type of the field in the source system. You can do this by checking the data dictionary (SE11) or the relevant table/view.
  Update Data Model: If the data type has changed, you may need to update the data model in the target system (e.g., InfoObject, DataSource) to reflect the new data type.
  Re-activate DataSource: After making changes to the data model, re-activate the DataSource in SAP BW or the relevant data extraction process.
  Adjust Transformations: If you are using transformations, ensure that the mappings and transformations are updated to accommodate the new data type.
  Test Data Transfer: After making the necessary adjustments, perform a test data transfer to ensure that the error is resolved.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like RSA1 (Data Warehousing Workbench) to manage InfoObjects and DataSources, and SE11 to check the data dictionary.
  SAP Notes: Check for any relevant SAP Notes that may address specific issues related to data type changes or provide guidance on handling this error.
  Documentation: Review SAP documentation on data extraction and data modeling to understand best practices and potential pitfalls.
  
  By following these steps, you should be able to resolve the RSAR703 error and ensure that your data extraction processes function correctly.
