Order Item Batch

When an order is submitted, all items in that order are flagged as batch #1. If that order is added to, all items in that addition will be flagged as batch #2. If the order is added to again, all items will be flagged as batch #3 and so forth.
Adding Items To An Order
To add items to an order (Add another batch) simply add the items to your cart and proceed to check out again. This will change the Order Status to Updated. See Order Status to see which statuses allow for adding to an existing order.
