• What is the cause and solution for SAP error message RSAR388 - Several source systems possible, source system & used ?

  The SAP error message RSAR388 indicates that there are multiple source systems available for a particular data extraction process, and it is unclear which source system is being used. This can occur in scenarios involving SAP BW (Business Warehouse) when trying to extract data from multiple source systems that have similar configurations or data sources.
  Cause:
  
  Multiple Source Systems: The error typically arises when there are multiple source systems defined in the SAP BW system that can provide the same data. This can happen if you have multiple connections to different SAP ERP systems or if you have multiple logical systems configured.
  Ambiguity in Data Source: The system cannot determine which source system to use for the data extraction, leading to confusion in the data flow.
  
  Solution:
  To resolve the RSAR388 error, you can take the following steps:
  
  
  Identify Source Systems: Check the source systems configured in your SAP BW system. You can do this by navigating to the DataSource in the SAP BW system and reviewing the source system settings.
  
  
  Specify Source System: If you are using a specific data extraction process (like a DataSource or InfoPackage), ensure that you explicitly specify which source system to use. This can often be done in the settings of the InfoPackage or the DataSource.
  
  
  Adjust DataSource Settings: If necessary, adjust the settings of the DataSource to ensure that it is correctly linked to the intended source system. You may need to modify the DataSource or create a new one if the current configuration is ambiguous.
  
  
  Check Logical System Configuration: Ensure that the logical system configuration is correct and that there are no duplicate entries or misconfigurations that could lead to ambiguity.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific DataSource or extraction process you are working with. There may be specific guidelines or best practices for handling multiple source systems.
  
  
  Testing: After making the necessary adjustments, perform a test extraction to ensure that the error is resolved and that data is being pulled from the correct source system.
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like RSA1 (Data Warehousing Workbench) to manage DataSources and InfoProviders.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Documentation: Refer to SAP Help Portal for detailed documentation on data extraction processes and handling multiple source systems.
