Pricing communication beetwen Fiori & CRM

[former_member451547]

Hello boys,

Does anyone know how to configure pricing communication for Fiori App with SAP CRM?

We have Z Odata service which uses a batch request for create\update an opportunity. But we a facing a problem with pricing calculation. Since the principle of request-response interaction, so that we cannot use crm_order_maintain with its buffer data.
One of the possible solutions is to create a Z service to simulate the creation of opportunity and then to get pricing calculations from a buffer next to call rollback.
But we do not want to manipulate such a complex object at runtime in order to get a side effect in the form of price calculations. Perhaps is there some class or FM that can do this action without using the operation(opportunity) or its items?

As I know there is an API for S4 for pricing, maybe you know a similar API for SAP CRM?

P.S. sorry for the bad English

P.S.S. guys, I really count on your help
