• What is the cause and solution for SAP error message /OSP/A_MSG148 - RFC destination &1 should select No Logon and Send SAP LogonTicket ?

  The SAP error message /OSP/A_MSG148 RFC destination &1 should select No Logon and Send SAP LogonTicket typically occurs in the context of using SAP's Single Sign-On (SSO) capabilities, particularly when dealing with Remote Function Calls (RFC) between systems.
  Cause:
  This error indicates that the RFC destination specified (denoted by &1) is configured incorrectly for SSO. Specifically, it suggests that the destination is set to require a logon, but it should be configured to use a Logon Ticket instead. This is often a configuration issue in the RFC destination settings.
  Solution:
  To resolve this error, you need to adjust the settings of the RFC destination in the SAP system. Here are the steps to do this:
  
  
  Access the RFC Destination Configuration:
  
  Go to transaction code SM59 in the SAP GUI.
  Locate the RFC destination that is causing the error (replace &1 with the actual name of the RFC destination).
  
  
  
  Edit the RFC Destination:
  
  Select the RFC destination and click on the "Change" button.
  Navigate to the "Logon & Security" tab.
  
  
  
  Adjust Logon Settings:
  
  Set the "Logon Method" to "No Logon" (or "No Logon and Send SAP Logon Ticket" depending on your version).
  Ensure that the option to send a Logon Ticket is enabled.
  
  
  
  Save the Changes:
  
  After making the necessary changes, save the configuration.
  
  
  
  Test the RFC Connection:
  
  Use the "Connection Test" feature in SM59 to verify that the connection works without errors.
  
  
  
  Related Information:
  
  SAP Single Sign-On (SSO): This feature allows users to log in once and gain access to multiple SAP systems without needing to log in again. It typically uses SAP Logon Tickets for authentication.
  Logon Tickets: These are tokens that are generated during the initial logon and can be used for subsequent logins to other SAP systems.
  Documentation: Refer to SAP's official documentation on configuring SSO and RFC destinations for more detailed guidance.
  
  Additional Considerations:
  
  Ensure that the systems involved in the RFC communication are properly configured for SSO.
  Check for any network issues or firewall settings that might affect the communication between the systems.
