• What is the cause and solution for SAP error message RSM1345 - DataSource & from source system & is NOT a new DataSource ?

  The SAP error message RSM1345 indicates that the DataSource you are trying to replicate or use is not recognized as a new DataSource in the system. This typically occurs during the process of data extraction or when setting up a DataSource in SAP BW (Business Warehouse) from a source system.
  Cause:
  
  DataSource Already Exists: The DataSource you are trying to replicate already exists in the BW system. This can happen if the DataSource was previously created or replicated, and you are attempting to replicate it again without making any changes.
  Incorrect Configuration: There may be an issue with the configuration of the DataSource in the source system or BW system.
  Transport Issues: If the DataSource was transported from another system, it may not have been properly activated or configured in the target system.
  
  Solution:
  
  Check Existing DataSources: Verify if the DataSource already exists in the BW system. You can do this by navigating to the DataSource maintenance area in the SAP BW system (Transaction Code: RSA1).
  Use Existing DataSource: If the DataSource already exists, you can use it instead of trying to create a new one. Ensure that it is properly configured and activated.
  Delete and Recreate: If you need to make changes to the DataSource, you may need to delete the existing DataSource and then recreate it. Be cautious with this approach, as it may affect existing data models or processes.
  Check Transport Requests: If the DataSource was transported, ensure that all necessary transport requests have been successfully imported and activated in the target system.
  Consult Documentation: Review the SAP documentation or notes related to the specific DataSource for any additional configuration steps or prerequisites.
