• What is the cause and solution for SAP error message RSDS179 - DataSource &1(&2) must be activated ?

  The SAP error message RSDS179 indicates that a DataSource (identified by &1 and &2) must be activated before it can be used. This typically occurs in the context of SAP BW (Business Warehouse) or SAP BW/4HANA when working with DataSources that are not yet activated in the system.
  Cause:
  The error occurs because the DataSource has not been activated in the SAP system. Activation is necessary for the DataSource to be available for data extraction and loading processes. This can happen for several reasons:
  
  The DataSource was newly created and has not been activated yet.
  The DataSource was modified, and the changes require reactivation.
  The DataSource was deactivated for some reason.
  
  Solution:
  To resolve the RSDS179 error, you need to activate the DataSource. Here are the steps to do this:
  
  
  Access the DataSource:
  
  Go to the SAP GUI and navigate to the DataSource using transaction code RSA1 (Data Warehousing Workbench).
  In the Data Warehousing Workbench, go to the "Modeling" section and find the DataSource in the relevant InfoSource or InfoPackage.
  
  
  
  Activate the DataSource:
  
  Right-click on the DataSource and select "Activate" from the context menu.
  Alternatively, you can use transaction code RSA2 to directly access the DataSource and activate it from there.
  
  
  
  Check Activation Status:
  
  After activation, you can check the status of the DataSource to ensure it is now active. You can do this by looking for an activation status indicator or by trying to use the DataSource in a data extraction process.
  
  
  
  Recheck the Process:
  
  Once activated, re-run the process that triggered the error to confirm that the issue has been resolved.

  DataSource Types:
  
  DataSources can be created for various sources, including SAP ERP, flat files, and other databases.
  
  
  Activation Process:
  
  Activation involves generating the necessary structures in the BW system to allow data extraction.
  
  
  Troubleshooting:
  
  If the DataSource still does not work after activation, check for any additional errors or logs that may indicate other issues, such as authorization problems or data model inconsistencies.
  
  
  
  By following these steps, you should be able to resolve the RSDS179 error and successfully activate the DataSource for use in your SAP BW environment.
