• What is the cause and solution for SAP error message RJ120 - Only transaction data can be converted into a DataSource at this time ?

  The SAP error message RJ120, which states "Only transaction data can be converted into a DataSource at this time," typically occurs when you are trying to create or convert a DataSource in SAP BW (Business Warehouse) that is not compatible with the requirements for transaction data.
  Cause:
  
  Data Type Mismatch: The DataSource you are trying to create or convert is likely based on master data or some other non-transactional data type. SAP BW DataSources are designed to handle specific types of data, and this error indicates that the system expects transaction data.
  Incorrect Source System Configuration: The source system may not be properly configured to allow the extraction of transaction data.
  DataSource Definition: The DataSource definition may not be set up correctly to handle the type of data you are trying to convert.
  
  Solution:
  
  Check DataSource Type: Ensure that the DataSource you are trying to create or convert is indeed meant for transaction data. If it is meant for master data or other types, you will need to create a different DataSource.
  Review Source System: Verify that the source system is correctly configured to allow the extraction of transaction data. This may involve checking the connection settings and ensuring that the necessary authorizations are in place.
  Create a New DataSource: If you need to extract transaction data, consider creating a new DataSource specifically designed for that purpose. Use the appropriate transaction codes (like RSA1) to create a new DataSource.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on creating DataSources and the types of data they can handle. This can provide insights into the correct setup and configuration.
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as there may be fixes or enhancements related to DataSource handling.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as RSA1 (Data Warehousing Workbench), RSA3 (DataSource Test), and others that are used for managing DataSources in SAP BW.
  SAP Notes: Check SAP Notes for any known issues or additional guidance related to the RJ120 error message. SAP Notes often provide specific solutions or workarounds for common problems.
  SAP Community: Engage with the SAP Community forums or support channels for additional insights and experiences from other users who may have encountered similar issues.
