Click in the toolbar to run the script and reload data in the app. The app is automatically saved before loading the data.
The Data load progress dialog is displayed, and you can Abort the load. When the data load has completed, the dialog is updated with status (Finished successfully or Data load failed) and a summary of possible errors and warnings, such as for synthetic keys. The summary is also displayed in Output, if you want to view it after the dialog is closed.
