• What is the cause and solution for SAP error message RSM085 - No active DataSource '&' for source system '&'; action terminated ?

  The SAP error message RSM085 indicates that there is no active DataSource available for the specified source system. This error typically occurs in the context of SAP BW (Business Warehouse) when trying to extract data from a source system, such as SAP ERP or other data sources.
  Cause:
  
  Inactive DataSource: The DataSource you are trying to use is not active in the source system.
  Incorrect Source System Configuration: The source system may not be properly configured or connected to the BW system.
  DataSource Deletion: The DataSource may have been deleted or not created in the source system.
  Transport Issues: If the DataSource was transported from another system, it may not have been activated in the target system.
  Authorization Issues: The user may not have the necessary authorizations to access the DataSource.
  
  Solution:
  
  
  Check DataSource Activation:
  
  Go to the source system (e.g., SAP ERP) and check if the DataSource is active. You can do this using transaction code RSA1 in the BW system or RSA2 in the source system.
  If the DataSource is inactive, activate it.
  
  
  
  Verify Source System Configuration:
  
  Ensure that the source system is correctly configured in the BW system. Check the settings in transaction RSA1 under the "Source Systems" section.
  Make sure the connection to the source system is working properly.
  
  
  
  Recreate or Transport DataSource:
  
  If the DataSource is missing, you may need to recreate it in the source system or transport it from another system if it was deleted.
  
  
  
  Check Authorizations:
  
  Ensure that the user executing the data extraction has the necessary authorizations to access the DataSource.
  
  
  
  Check for Transport Issues:
  
  If the DataSource was recently transported, ensure that all necessary objects were included in the transport request and that they were activated in the target system.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
