You need to refresh command interfaces when the interfaces of objects they refer to have changed.
In the test data editor, the Refresh buttons and the menu entry Edit ®Refresh All have the same function. They refresh all the command interfaces in the test data container.
The Refresh button in the parameter list only refreshes the command interfaces listed there.
Edit ®Refresh All first performs a check on the command editor, creates command interfaces that are not already listed in the parameter list, and then refreshes the command interfaces.
In the test configuration editor, the Refresh button and the menu entry Refresh have the same function. They refresh all the command interfaces in the test configuration.
