• What is the cause and solution for SAP error message RSOA304 - No source system selected ?

  The SAP error message RSOA304 "No source system selected" typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when trying to execute a query or data extraction process without a valid source system being defined. This can happen in various scenarios, such as when creating or executing a data source, InfoPackage, or query.
  Cause:
  
  Missing Source System: The source system from which data is to be extracted is not defined or selected in the relevant settings.
  Incorrect Configuration: The configuration of the data source or InfoProvider may not be set up correctly, leading to the system not recognizing any source system.
  Authorization Issues: The user executing the query or data extraction may not have the necessary authorizations to access the source system.
  Technical Issues: There may be technical issues or inconsistencies in the system that prevent the source system from being recognized.
  
  Solution:
  
  
  Check Source System Configuration:
  
  Go to the SAP BW system and check the configuration of the source system in the Data Warehousing Workbench (transaction RSA1).
  Ensure that the source system is correctly defined and activated.
  
  
  
  Select the Source System:
  
  When executing a query or data extraction, ensure that you have selected the appropriate source system in the selection screen or settings.
