  The SAP error message /OSP/MSG508 indicates that there is an issue with the configuration of the RFC (Remote Function Call) destination in your SAP system. Specifically, it suggests that the RFC destination should be set to "No Logon" and configured to send an SAP Logon Ticket.
  Cause:
  This error typically arises when:
  
  The RFC destination is not configured correctly for the intended authentication method.
  The system is expecting a Logon Ticket for Single Sign-On (SSO) but is not receiving it due to incorrect settings.

  Solution:
  To resolve this issue, follow these steps:
  
  
  Access the RFC Destination Configuration:
  
  Go to transaction code SM59 in your SAP GUI.
  Locate the RFC destination that is causing the error.

  Check the Connection Parameters:
  
  Ensure that the connection parameters are correctly set up for the destination.
  Verify that the target system is configured to accept Logon Tickets.
  
  
  
  Test the Connection:
  
  After making the changes, use the "Connection Test" button to verify that the RFC destination is working correctly.
  
  
  
  Review SSO Configuration:
