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
