Enhancing order.quote.breakup array

[92shreyansh]

Have observed that in 1.x specification we have added item object as part of the breakup object.

Understanding is to enable to map a specificat breakup title and value to a item eg: tax, offer_discount, convenience fees etc. Hence enabling a very better drilled down version of breakup available on the protocal rather than aggregated breakup at order level.

However in certain usecases there are requirement to have these breakup also availabe at fulfilment level as so currently the specification have no other mechanism to identify the price of a fulfilment. Just to add to this, price of a fulfilment is a function of the base fulfilment present in the fulfillments array and the items associated to it. This association of fulfilment and items is already handled at item level using fulfilment_ids.

To handle the above usecase of fulfilment price wanted to open the discussion with a praposal

1. add 2 attributes at the break up object

• reference_type : [optional] string type with values like (item, fulfilment)
• reference_id: [optional] string type with value as id of the refrenced element
  Considering default refrence is to Order level break up

2. remove item object from break up as it would just carry redundant information and can always be referenced with above 2 attributes

Would like to hear more on this, and validate the usecases beyond the above mentioned
