Partial invoicing in Magento 2 - how to update order line items with which items to invoice via csv?
For example, let's say I have an order that has 4 items on it. 2 of those items are on back order. So, I want to invoice and ship the other 2 items.
How can I, via csv, invoice those 2 items and update only the tracking number for those 2 items?
Thank you.
