We have been using classes on the line item level to track lot numbers of the products we make. We created them in custom templates to show up on every invoice/receipt. If an item doesn't need to be tracked, we just leave the class on that item blank. We have been manually inputting each class for the items on every invoice/receipt. We can then run a report by class to show everyone who received a certain lot number of that item. I just discovered creating custom fields in items. My question is, if I create a custom field in an item called class, then put in the lot number (which is already a class we have created), and check USE, will that number automatically show up on the invoice/receipt on the line item level under class whenever that product is selected? I know there is lot number tracking in Enterprise, but we are using Premier.
