• What is the cause and solution for SAP error message STREX199 - RFC destination &1 does not exist ?

  The SAP error message STREX199, which states "RFC destination &1 does not exist," typically occurs when the system is trying to access a Remote Function Call (RFC) destination that has not been defined in the SAP system. This can happen in various scenarios, such as when trying to execute a remote function module or when a program is attempting to connect to another SAP system or external system.
  Cause:
  
  Missing RFC Destination: The specified RFC destination does not exist in the SAP system.
  Incorrect Configuration: The RFC destination may be incorrectly configured or may have been deleted.
  Authorization Issues: The user may not have the necessary authorizations to access the RFC destination.
  Typographical Error: There may be a typo in the name of the RFC destination being referenced.
  
  Solution:
  
  
  Check RFC Destination:
  
  Go to transaction code SM59 (RFC Destinations).
  Look for the RFC destination that is mentioned in the error message. If it does not exist, you will need to create it.
  
  
  
  Create or Modify RFC Destination:
  
  If the RFC destination is missing, you can create it by clicking on the "Create" button in SM59.
  Fill in the required fields, such as the destination name, connection type, target host, and system number.
  Test the connection to ensure it is working correctly.
  
  
  
  Check for Typographical Errors:
  
  Verify that the name of the RFC destination is spelled correctly in the program or configuration that is calling it.
  
  
  
  Authorization Check:
  
  Ensure that the user has the necessary authorizations to access the RFC destination. This can be checked in transaction code SU01 (User Maintenance) or by consulting with your security team.
  
  
  
  Check System Configuration:
  
  If the RFC destination points to another SAP system, ensure that the target system is up and running and that network connectivity is established.
  
  
  
  Review Logs:
  
  Check the system logs (transaction code SM21) for any additional error messages that might provide more context about the issue.
