• What is the cause and solution for SAP error message /SCWM/ERPINTEGRATION860 - Communication to logical system &1 via RFC is not supported ?

  The SAP error message /SCWM/ERPINTEGRATION860 Communication to logical system &1 via RFC is not supported typically occurs in the context of SAP Extended Warehouse Management (EWM) when there is an issue with the communication setup between the EWM system and the ERP system (like SAP ECC or S/4HANA). This error indicates that the system is trying to communicate with a logical system that is not configured correctly for RFC (Remote Function Call) communication.
  Causes:
  
  Incorrect Logical System Configuration: The logical system specified in the error message may not be set up correctly in the SAP system.
  Missing RFC Destination: The RFC destination for the logical system may not exist or may not be configured properly.
  Authorization Issues: The user or system may not have the necessary authorizations to perform the RFC communication.
  Network Issues: There may be network connectivity issues preventing communication between the systems.
  Incorrect EWM Configuration: The EWM system may not be configured to communicate with the specified logical system.
  
  Solutions:
  
  
  Check Logical System Configuration:
  
  Go to transaction SM59 in the SAP GUI.
  Verify that the RFC destination for the logical system mentioned in the error message exists and is configured correctly.
  Ensure that the logical system is defined in transaction BD54 (Maintain Logical Systems).
  
  
  
  Create or Update RFC Destination:
  
  If the RFC destination does not exist, create it in SM59.
  If it exists but is not configured correctly, update the settings, ensuring that the connection type is set to "T" (TCP/IP) and that the target host and service are correct.
  
  
  
  Check Authorizations:
  
  Ensure that the user or system has the necessary authorizations to perform RFC calls. This may involve checking roles and profiles assigned to the user.
  
  
  
  Test RFC Connection:
  
  Use the "Connection Test" feature in SM59 to verify that the RFC connection can be established successfully.
  
  
  
  Review EWM Configuration:
  
  Check the EWM configuration settings to ensure that the logical system is correctly assigned and that all necessary settings for integration with the ERP system are in place.
  
  
  
  Network Troubleshooting:
  
  If the above steps do not resolve the issue, check for any network-related problems that may be affecting communication between the systems.
