  The SAP error message PS4S011 indicates an RFC (Remote Function Call) communication error, specifically stating that the server identified as "&1" is excluded from processing. This error typically arises in scenarios where there is an issue with the communication between the SAP system and the application server or when the server is not available for processing requests.
  Causes:
  
  Network Issues: There may be network connectivity problems between the SAP application server and the database or other servers.
  Server Configuration: The server may be incorrectly configured or not properly registered in the SAP system.
  Server Status: The server might be down or in a state that prevents it from processing requests (e.g., maintenance mode).

  Authorization Issues: The user or system may not have the necessary authorizations to communicate with the specified server.
