  Use the eCATT Workbench: Open the eCATT Workbench (transaction code SECATT) and navigate to the test script you want to modify. Make your changes there.
  External Tool: If you are using an external tool (like a text editor), ensure that you are editing the correct script file and that you save your changes properly.
  Re-import the Script: If you have made changes externally, you may need to re-import the script into the eCATT Workbench to ensure that the changes are recognized by the system.
  Check for Locks: Ensure that the test script is not locked by another user or process, which might prevent you from making changes.
  
  Related Information:
  
  eCATT Documentation: Refer to the official SAP documentation for eCATT for detailed instructions on how to create and manage test scripts.
