When you define a group of subscriptions at one time, the Add Subscription Wizard displays a dialog to warn of possible data loss, such as if the specified destination table already exists and would be deleted when this subscription is run. The name of the subscription for which the warning applies appears in the title bar of the dialog.
You can choose Yes to ignore the warning for the specified subscription, Yes to All to ignore the warning for any of the subscriptions in the group, No to discard the group of subscriptions, or Cancel to cancel the save and return to the Subscription Wizard.
