Pop up or End Form in a Data flow

Try adding a "show popup" step at the end of the data flow. This will show a pop up in the right corner with whatever message you want every time the data flow runs. Unfortunately, you wont be able to use a traditional form or end form in your data flow because they cant contain any asynchronous steps, such as forms or other UI elements, which is why a pop up is the only real work around if you want to stick with your data flow.

One option, however, would be to change your data flow to a sub dialog instead, which would be launched from your button via the same click action and that would allow you to populate a form as well as use other design elements, but this would require some changes to your form/flow. .
