• What is the cause and solution for SAP error message RJ020 - Data type not supported by source system ?

  The SAP error message RJ020, which states "Data type not supported by source system," typically occurs in the context of data extraction or data transfer processes, particularly when using SAP Data Services or SAP BW (Business Warehouse). This error indicates that the data type of a field in the source system is not compatible with the data types supported by the target system or the data processing framework.
  Causes:
  
  Incompatible Data Types: The source system may have a data type that is not recognized or supported by the target system. For example, certain complex data types or custom data types may not have a direct equivalent in SAP BW or other target systems.
  Data Type Mismatches: There may be a mismatch in the expected data type (e.g., trying to transfer a string where a numeric value is expected).
  Configuration Issues: Incorrect configuration in the data extraction or transformation process can lead to this error.
  Version Compatibility: The source system may be using a version of a data type that is not compatible with the version of the target system.
  
  Solutions:
  
  Check Data Types: Review the data types in the source system and ensure they are compatible with the target system. You may need to modify the data types in the source or target system to ensure compatibility.
  Data Mapping: If you are using a data transformation tool, ensure that the data mapping is correctly defined. You may need to explicitly convert data types during the extraction or transformation process.
  Update Data Services: If you are using SAP Data Services, ensure that you are using the latest version, as updates may include support for additional data types.
  Custom Data Types: If the source system uses custom data types, consider creating a mapping or transformation logic to convert these to standard data types that are supported by the target system.
  Consult Documentation: Refer to the SAP documentation for both the source and target systems to understand the supported data types and any limitations.
  Error Logs: Check the error logs for more detailed information about the specific data type causing the issue. This can help in identifying the exact field or data element that is problematic.
