This error indicates that there are no requests available for initialization or switching in the data transfer process (DTP) or InfoPackage.
  Cause:
  
  No Initialization Requests: The error often arises when there are no initialization requests scheduled for the data source. This can happen if the data source has not been initialized yet or if the initialization process has not been executed.

  Monitor Data Source: Verify that the data source is active and that there is data available for extraction. You can check the data source in the SAP BW system to ensure it is functioning correctly.
  Check for Errors: Look for any other error messages or logs that might provide additional context about why the initialization requests are not being generated.
