Sync a partial refund from NetSuite to Magento without refunding the Item

Problem: Exporting a partial refund without refunding the item.

• NetSuite Item to track Magento Adjustment Refund as a line item.
• NetSuite Item to track Magento Fee as a line item.

• Adjustment Refund line item should be used to increase the refund.
• Adjustment Fee line item should be used if the customer wants to refund a smaller amount. 

Create the NetSuite Cash Refund or Credit Memo:

• Update the quantity of the Refund item to 0.
• Add the Adjustment Refund or the Adjustment Fee item and update the amount.

Note:

An upgrade to the M2.2 version is required for product refunds with a "0" quantity.
