  Cause:
  
  Missing Subscreen Definition: The error indicates that the system is trying to access a subscreen that has not been defined in the configuration. This could be due to a missing entry in the relevant customizing settings.
  Incorrect Configuration: The configuration for the selection screen block may not be set up correctly, leading to the system being unable to find the specified subscreen.
  Transport Issues: If the configuration was transported from one system to another (e.g., from development to production), there may have been issues during the transport that caused the subscreen definition to be lost or not properly imported.
  
  Solution:
  
  
  Check Configuration:

  Review Transport Requests:
  
  If the issue arose after a transport, check the transport logs to ensure that all necessary objects were included and correctly imported. You may need to re-transport the missing objects.
  
  
  
  Debugging:
  
  If you have access to debugging tools, you can set breakpoints in the relevant AIF function modules to trace where the error is occurring and gather more context about the missing subscreen.
