I need some help adding a function to a standard java code I received for Shopify. Tracking = priority for tech approval. - discountAmount will need to only be mapped to the order level discount - unitPrice and unitPriceLessTax will need to be mapped to the post item level discount. What ‘s requested: Tracking = priority for tech approval. - Using item level discounts so app won’t work. (I have the standard code) - but not dure how to change this part: o discountAmount will need to only be mapped to the order level discount (currently I believe it uses all discounts) o unitPrice and unitPriceLessTax will need to be mapped to the post item level discount (if 10% off lipstick is used the prices should reflect that discount and other items in the cart would not) I have the standard code available if someone knowledgeable can help?
