• What is the cause and solution for SAP error message /SCWM/CCHECK202 - No RFC connection for the destination logical system ?

  The SAP error message /SCWM/CCHECK202 No RFC connection for the destination logical system typically indicates that there is an issue with the Remote Function Call (RFC) connection to a specified logical system in the SAP system. This error is often encountered in the context of SAP Extended Warehouse Management (EWM) or when integrating with other SAP systems.
  Cause:
  
  Missing RFC Destination: The logical system you are trying to connect to does not have a corresponding RFC destination defined in the SAP system.
  Incorrect Configuration: The RFC destination may be incorrectly configured, such as wrong connection parameters (like host, service, or system number).
  Network Issues: There may be network connectivity issues preventing the SAP system from reaching the destination logical system.
  Authorization Issues: The user or system may not have the necessary authorizations to establish the RFC connection.
  Logical System Not Defined: The logical system may not be defined in the system landscape or may not be properly assigned to the client.
  
  Solution:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Look for the RFC destination that corresponds to the logical system mentioned in the error message.
  If it does not exist, create a new RFC destination with the correct parameters.
  
  
  
  Verify Configuration:
  
  Ensure that the RFC destination is configured correctly with the right connection type (e.g., TCP/IP), host, and service.
  Test the connection using the "Connection Test" option in SM59.
  
  
  
  Check Logical System Configuration:
  
  Go to transaction SALE and navigate to Basic Settings -> Logical System -> Define Logical System.
  Ensure that the logical system is defined and correctly assigned to the client.
  
  
  
  Network Connectivity:
  
  Check for any network issues that might be preventing the connection. This can include firewall settings, network routing, or DNS issues.
  
  
  
  Authorization Check:
  
  Ensure that the user or system has the necessary authorizations to perform the RFC call. This may involve checking roles and profiles assigned to the user.
  
  
  
  Review System Logs:
  
  Check the system logs (transaction SM21) for any additional error messages or warnings that might provide more context about the issue.
