Listing 8.16 Executing an Action
When you test this in Transaction /BOBF/TEST_UI, the result is truly beautiful.
Call up a list of all your mo nsters, select one, click Execute Action, and you’ll
magically get a pop-up asking you to fill in the import parameter for the action
(Figure 8.23). Once you’ve done that, the howling commences (Figure 8.24).
As you can imagine, being able to te st a user command before you have even
started writing the main application and are still really at the data modeling stage
is a wonderful step forward. The earlier you can do testing, the better.
