Smart SAP Assistant

• What is the cause and solution for SAP error message ECATT691 - eCATT command &3 only allowed using 'Trusted RFC' (RFC Dest:&4->&1:&2) ?

  The SAP error message ECATT691 indicates that an eCATT (extended Computer Aided Test Tool) command is being executed in a context that does not allow it, specifically when it is not using a "Trusted RFC" connection. This error typically arises when you are trying to execute a test script that requires a trusted connection to the target system.
  Cause:
  The error occurs because:
  
  The eCATT command is being executed using a non-trusted RFC destination.
  The RFC destination specified does not have the necessary authorizations or is not configured as a trusted connection.
  The eCATT script is trying to perform actions that require elevated permissions or specific configurations that are only available through trusted connections.
  
  Solution:
  To resolve the ECATT691 error, you can take the following steps:
  
  
  Check RFC Destination Configuration:
  
  Go to transaction SM59 in the SAP GUI.
  Locate the RFC destination that is being used in the eCATT script.
  Ensure that the destination is configured as a "Trusted RFC". This typically involves setting the "Trusted" checkbox in the RFC destination settings.
  
  
  
  Create a Trusted RFC:
  
  If the RFC destination is not trusted, you may need to create a new RFC destination or modify the existing one.
  Ensure that the user credentials used for the RFC connection have the necessary authorizations to execute the eCATT commands.
  
  
  
  User Authorizations:
  
  Verify that the user executing the eCATT script has the necessary authorizations in both the source and target systems.
  Check roles and profiles assigned to the user to ensure they have the required permissions.
  
  
  
  Test the Connection:
  
  After making changes, test the RFC connection from SM59 to ensure it is working correctly.
  You can also use the "Connection Test" feature in SM59 to verify that the trusted connection is functioning as expected.
  
  
  
  Review eCATT Script:
  
  Ensure that the eCATT script is correctly configured and that it is intended to run in the context of a trusted RFC connection.
