• What is the cause and solution for SAP error message ESH_ADAPT_MSG050 - The authentication method for the RFC destination &1 requires logon data ?

  The SAP error message ESH_ADAPT_MSG050 indicates that the authentication method for the specified RFC (Remote Function Call) destination requires logon data, but this data is either missing or not properly configured. This error typically arises when trying to connect to an RFC destination that requires credentials, but those credentials have not been provided or are incorrect.
  Cause:
  
  Missing Logon Data: The RFC destination is configured to use a specific authentication method (like Basic Authentication or Secure Network Communications) that requires user credentials, but these credentials have not been set up.
  Incorrect Configuration: The RFC destination may be incorrectly configured, leading to a mismatch between the expected authentication method and the provided logon data.
  Authorization Issues: The user account being used may not have the necessary authorizations to access the RFC destination.
  Network Issues: Sometimes, network issues can prevent the proper authentication process from completing.
  
  Solution:
  
  
  Check RFC Destination Configuration:
  
  Go to transaction SM59 in the SAP GUI.
  Locate the RFC destination that is causing the error.
  Check the settings under the "Logon & Security" tab to ensure that the correct authentication method is selected and that the necessary logon data (username and password) is provided.
  
  
  
  Provide Logon Data:
  
  If the authentication method requires a username and password, ensure that these are correctly entered in the RFC destination configuration.
  If using a secure connection (like SNC), ensure that the SNC settings are correctly configured.
  
  
  
  Test the Connection:
  
  After making changes, use the "Connection Test" feature in transaction SM59 to verify that the RFC destination can be reached and that the authentication is successful.
  
  
  
  Check User Authorizations:
  
  Ensure that the user account being used has the necessary authorizations to access the RFC destination. This may involve checking roles and profiles assigned to the user.
  
  
  
  Review Network Settings:
  
  If the issue persists, check for any network-related issues that might be affecting the connection to the RFC destination.
  
  
  
  Related Information:
  
  RFC Destinations: These are configurations in SAP that define how to connect to other SAP systems or external systems.
  Authentication Methods: Common methods include Basic Authentication, SNC, and others. Each method has specific requirements for logon data.
  Transaction Codes:
  
  SM59: Used to manage RFC destinations.
  SU01: Used to manage user accounts and authorizations.
  
  
  SAP Notes: Check for any relevant SAP Notes that might address specific issues related to RFC connections and authentication.
  
  By following these steps, you should be able to resolve the error message ESH_ADAPT_MSG050 and successfully connect to the required RFC destination.
