• What is the cause and solution for SAP error message R8356 - The delta process &1 does not exist ?

  The SAP error message R8356, which states "The delta process &1 does not exist," typically occurs in the context of SAP BW (Business Warehouse) or SAP BI (Business Intelligence) when dealing with delta loads. This error indicates that the system is unable to find the specified delta process for the data source or InfoPackage you are trying to execute.
  Causes:
  
  Non-existent Delta Process: The delta process specified in the error message does not exist in the system. This could be due to a misconfiguration or an incorrect reference.
  Data Source Configuration: The data source may not be properly configured for delta extraction. If the delta mechanism is not set up correctly, the system will not recognize the delta process.
  Transport Issues: If the data source or related objects were transported from one system to another, the delta process might not have been included or activated in the target system.
  Deletion of Delta Process: The delta process may have been deleted or deactivated in the system.
  
  Solutions:
  
  
  Check Delta Process Configuration:
  
  Go to the DataSource in the SAP BW system and check if the delta process is correctly defined.
  Ensure that the delta process is activated and properly configured.
  
  
  
  Recreate Delta Process:
  
  If the delta process does not exist, you may need to recreate it. This can be done by going to the DataSource settings and reactivating the delta process.
  
  
  
  Check InfoPackage Settings:
  
  Verify the settings of the InfoPackage that is trying to execute the delta load. Ensure that it is pointing to the correct DataSource and that the delta process is specified correctly.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, check the transport logs to ensure that all necessary objects were transported correctly. You may need to re-transport the missing objects.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to the specific DataSource you are working with to ensure that all necessary steps for delta configuration have been followed.
  
  
  
  System Logs:
  
  Check the system logs (transaction SLG1) for any additional error messages or warnings that might provide more context about the issue.
  
  
  
  Related Information:
  
  Delta Mechanism: Understand how delta extraction works in SAP BW. Delta processes are used to extract only the changes (new or modified records) since the last extraction, which is more efficient than full loads.
  SAP Notes: Search for relevant SAP Notes in the SAP Support Portal that might address known issues or provide patches related to this error.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they found effective.
  
  By following these steps, you should be able to diagnose and resolve the R8356 error in your SAP BW or BI environment.
