• What is the cause and solution for SAP error message 2L421 - Destination &1 is not defined in system &2, client &3 ?

  The SAP error message 2L421 indicates that a destination (usually a logical destination for communication, such as an RFC destination) is not defined in the specified system and client. This error typically arises when trying to execute a function that requires communication with another system, but the necessary configuration for that communication is missing.
  Cause:
  
  Missing RFC Destination: The specified destination is not defined in the SAP system.
  Incorrect Configuration: The destination might be incorrectly configured or pointing to the wrong system or client.
  Client-Specific Settings: The destination may exist in a different client but not in the one you are currently using.
  Transport Issues: If the destination was recently transported from another system, it may not have been properly set up in the target system.
  
  Solution:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 (RFC Destinations).
  Look for the destination name specified in the error message.
  If it does not exist, you will need to create it.
  
  
  
  Create or Modify RFC Destination:
  
  If the destination is missing, create a new RFC destination by clicking on "Create" and filling in the necessary details (like target host, system number, etc.).
  If it exists but is not configured correctly, modify it to ensure it points to the correct system and client.
  
  
  
  Check Client:
  
  Ensure you are in the correct client where the destination is defined. You can switch clients using the client selection screen.
  
  
  
  Transport Requests:
  
  If the destination was supposed to be transported, check the transport requests to ensure they were imported correctly.
  
  
  
  Authorization:
  
  Ensure that you have the necessary authorizations to access the RFC destination.
  
  
  
  Testing:
  
  After creating or modifying the destination, test the connection using the "Test Connection" button in SM59 to ensure it is working correctly.
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  SM59: Manage RFC Destinations.
  SICF: Check if the service is active if the destination is related to HTTP services.
  
  
  
  Documentation: Refer to SAP Help documentation for detailed steps on configuring RFC destinations.
  
  
  Logs: Check system logs (transaction SM21) for any additional error messages that might provide more context.
  
  
  By following these steps, you should be able to resolve the error message 2L421 and ensure that the destination is properly defined in your SAP system.
