Open the Versions pane from model settings and select Import from the toolbar at the top.
Select Upload New File and browse for the file that contains the source data.
If you want to amend a file import that already exists, you can select a previous upload and then Edit.
Optionally, map source columns to the target properties from the grid in the Versions <icons-ads versions /> pane.
Select either:
Run Import, to run the import and save the import as an action.
A progress dialog displays as the import runs.
If you want to cancel the import, select Cancel in the top-right corner of the dialog.
OK, to save the import as an action, but not run it.
When the import completes, or if you cancel the import, an Import Completed dialog displays. This reports how many items imported successfully and any that did not. You can open the Details tab for a detailed report or select Close to exit the dialog.
