This error can arise during various activities, such as running a planning job, executing a heuristic, or performing a simulation.
  Cause:
  
  Missing Action Network Definition: The action network specified in the error message (&1) has not been defined in the Customizing settings of the SAP system.
  Incorrect Configuration: The action network may have been incorrectly configured or deleted.
  Transport Issues: If the configuration was transported from another system, it may not have been included or may have failed during the transport process.

  Solution:
  
  
  Define the Action Network:

  Transport Check:

  If it was not transported, you may need to manually create it in the target system.
  
  
  
  Authorization Check:
  
  Ensure that the user executing the planning job has the necessary authorizations to access the action network.
  Check the user roles and profiles to confirm that they include the required permissions.
