This error indicates that the specified agent (represented by &1) is not recognized or registered with the systems that are trying to communicate with it.
  Causes:

  Configuration Errors: Incorrect configuration settings in the SAP system or in the agent's settings can lead to this error.

  Solutions:
  
  
  Check Agent Registration:
  
  Verify that the agent is correctly registered in the SAP system. You can do this by checking the transaction codes related to agents or background processing (e.g., SM37 for job monitoring).
  Use transaction SM59 to check the RFC destinations and ensure that the agent is listed and properly configured.
  
  
  
  Re-register the Agent:
  
  If the agent is not registered, you may need to register it again. This can often be done through the relevant configuration transactions or by using the appropriate SAP notes.
  
  
  
  Network Configuration:
  
  Ensure that there are no network issues preventing communication between the systems. Check firewalls, network settings, and ensure that the systems can ping each other.
  
  
  
  Review Configuration Settings:
  
  Check the configuration settings for the agent and ensure that they are consistent across all systems. This includes checking the logical system names and ensuring they match.
  
  
  
  Check Authorizations:
  
  Ensure that the user or system has the necessary authorizations to access the agent. This may involve checking roles and profiles assigned to the user.
