You use the Select Field dialog to specify which item field to be mapped to the issue-tracking template field that is currently selected in the Template Editor.
To call the dialog, click the ellipsis button of the Item Field column in the Template Editor dialog.
The Select Field dialog lists available item fields. Select the desired field and click OK. TestExecute will map the selected field to the selected template field. Cancel will close the dialog without any changes.
