S/4HANA - Add a Price Agreement to a Solution Quotation Item - Service Contract

[Alexander_0001]

Dear SAP Community,
at the moment I review all options for S/4HANA to add Pricing Agreement entries to a Solution Quotation Item of type Service Contract via an API call. I just want to check I there is relay no more standardized option

So I checked the SAP API Business Hub for Service Contract Item

Unfortunately I found just APIs to add Price Elements, Billing, Partner, Product, Item Reference, Text and others BUT NO API to add Pice Agreements direct to the item of a solution quotation of type Service Contract.

Now I am not sure if:

A) Price Elements can be used to add Price Agreements to the Service Contract ( I Dough it but correct me if I am wrong)

/A_BusSolnQtanSrvcContrItem(BusinessSolutionQuotation='{BusinessSolutionQuotation}',BusSolutionQuotationItem='{BusSolutionQuotationItem}')/to_PriceElement
Creates price element data for a specific service contract item.

B) It would be feasible via Master Agreement Item API

/MasterAgreement/{SrvcTransMstrAgrmtID}/_MasterAgreementItemTP
Add new entity to related _MasterAgreementItemTP

C) OR a custom API enhancement is needed here as (which I would like to avoid).

Look forward to your feedback.
Kind regards
Alexander
