• What is the cause and solution for SAP error message RSAU252 - Data source & not maintained (check your entries) ?

  The SAP error message RSAU252, which states "Data source & not maintained (check your entries)," typically occurs when there is an issue with the configuration or maintenance of a data source in the SAP system. This error can arise in various contexts, particularly when working with SAP BW (Business Warehouse) or when trying to extract data from a source system.
  Cause:
  
  Data Source Not Activated: The data source you are trying to use may not be activated in the SAP system.
  Incorrect Data Source Name: The data source name you are using may be incorrect or misspelled.
  Missing Configuration: The data source may not have been properly configured or maintained in the source system.
  Authorization Issues: The user may not have the necessary authorizations to access the data source.
  Transport Issues: If the data source was recently transported from another system, it may not have been properly set up in the target system.
  
  Solution:
  
  
  Check Data Source Activation:
  
  Go to transaction code RSA1 (Data Warehousing Workbench).
  Navigate to the "Data Sources" section and check if the data source is activated. If not, activate it.
  
  
  
  Verify Data Source Name:
  
  Double-check the name of the data source you are using. Ensure that it matches exactly with what is defined in the system.
  
  
  
  Maintain Data Source:
  
  If the data source is not maintained, you may need to configure it. This can be done in the same RSA1 transaction by selecting the data source and maintaining its settings.
  
  
  
  Check Authorizations:
  
  Ensure that the user has the necessary authorizations to access the data source. This can be checked with the help of your SAP security team.
  
  
  
  Review Transport Logs:

  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific data source for any additional configuration steps that may be required.
