• What is the cause and solution for SAP error message RSM2079 - DS &1 LS &2 set to "BY-Passing PSA" (mandatory); no InfoPackages allowed ?

  The SAP error message RSM2079 indicates that a DataSource (DS) and a Logical System (LS) are set to "By-Passing PSA" (Persistent Staging Area), which means that the data is being loaded directly into the target without being stored in the PSA first. This setting can lead to issues when trying to load data using InfoPackages, as the system does not allow InfoPackages to be used in this scenario.
  Cause:
  
  By-Passing PSA Setting: The DataSource is configured to bypass the PSA, which is typically done for performance reasons or when the data is not needed to be stored in the PSA.
  InfoPackage Configuration: The InfoPackage you are trying to use is not compatible with the DataSource's configuration, as it expects to load data into the PSA first.
  
  Solution:
  
  
  Change DataSource Settings:
  
  Go to the DataSource in the SAP BW system.
  Check the settings for the DataSource and see if the "By-Passing PSA" option is enabled.
  If you want to use InfoPackages, you will need to disable the "By-Passing PSA" option. This will allow the data to be loaded into the PSA first.
  
  
  
  Use Direct Load:
  
  If you intend to keep the "By-Passing PSA" setting, you will need to load data directly using a different method, such as using a process chain or a direct data load method that does not involve InfoPackages.
  
  
  
  Check InfoPackage Settings:
  
  Ensure that the InfoPackage is correctly configured for the DataSource you are using. If the DataSource is set to bypass the PSA, you may need to create a new InfoPackage that is compatible with this setting.
  
  
  
  Related Information:
  
  PSA (Persistent Staging Area): The PSA is a temporary storage area in SAP BW where data is stored before it is transformed and loaded into the final data targets. Bypassing the PSA can improve performance but may limit data processing capabilities.
  DataSource Configuration: Understanding how to configure DataSources in SAP BW is crucial for effective data loading. You can access the DataSource settings through the Data Warehousing Workbench.
  Performance Considerations: While bypassing the PSA can enhance performance, it may also complicate data management and troubleshooting. Consider the trade-offs before making changes to the DataSource settings.
  
  By addressing the configuration of the DataSource and the InfoPackage, you should be able to resolve the error message RSM2079 and successfully load your data.
