New dev notes 11/15
Currently there's a difference between FE and BE MS orders:
- for FE MS orders, the sales-ship-item stores product id of configurable-product; and store the SKU of the simple-product.
- for BE MS orders, the sales-ship-item stores product id of simple-product; and store SKU of the simple-product
Example: right is front-end, left is back-end. Same product orders; but data stored differently in database
