• What is the cause and solution for SAP error message /SCWM/ERPINTEGRATION104 - Error setting up RFC connection to &1 ?

  The SAP error message /SCWM/ERPINTEGRATION104 indicates an issue with setting up an RFC (Remote Function Call) connection to a specified system. This error typically arises in the context of SAP Extended Warehouse Management (EWM) when it attempts to communicate with the ERP system.
  Cause:
  
  RFC Destination Configuration: The RFC destination may not be correctly configured in the SAP system. This could include incorrect connection parameters, such as the target system's hostname, system number, client, user credentials, etc.
  Network Issues: There may be network connectivity issues between the SAP EWM system and the ERP system, preventing the RFC connection from being established.
  Authorization Issues: The user credentials used for the RFC connection may not have the necessary authorizations to connect to the target system.
  SAP Gateway Issues: The SAP Gateway service may not be running or may be misconfigured, which can prevent the establishment of the RFC connection.
  Firewall Restrictions: Firewalls or security settings may be blocking the required ports for RFC communication.
  
  Solution:
  
  
  Check RFC Destination:
  
  Go to transaction SM59 in the SAP GUI.
  Locate the RFC destination that corresponds to the target system.
  Verify that the connection parameters (such as hostname, system number, client, user, and password) are correct.
  Test the connection using the "Test Connection" button to ensure it can connect successfully.
  
  
  
  Network Connectivity:
  
  Ensure that there are no network issues between the two systems. You can use tools like ping or telnet to check connectivity to the target system's hostname and port.
  
  
  
  User Authorizations:
  
  Check that the user specified in the RFC destination has the necessary authorizations in the target system. This may involve checking roles and profiles assigned to the user.
  
  
  
  SAP Gateway:
  
  Ensure that the SAP Gateway service is running on both systems. You can check this using transaction SMGW.
  
  
  
  Firewall Settings:
  
  Verify that any firewalls between the two systems allow traffic on the required ports for RFC communication (typically port 3200 for SAP systems).
  
  
  
  Check Logs:
  
  Review the system logs for any additional error messages that may provide more context about the issue. You can check transaction SM21 for system logs and SLG1 for application logs.
