How do I register gowns sold to an event

Go to Inventory Categories Maintenance form and check Track on the inventory category(s) that sales should be tracked for.

Now, when any item with this category is sold to a member of any event, it is automatically marked REGISTER? on the sales ticket.

The operator will be warned if you try to sell the same item to two members of the event. You can review the items registered by clicking the Show Reg. Sales button on the Members Tab of the Event form.
