How to Fulfill salesorder using XRM Tooling

Hi,

I'm migrating data into Dynamics 365 (in O365)

I'm trying to Fulfill my imported Orders using XRM Tooling library. I'm using UpdateStateAndStatusForEntity method.

Unfortunately it generates the error:

This message can not be used to set the state of SalesOrder to Fulfilled.  In order to set state of SalesOrder to Fulfilled, use the FulfillSalesOrderRequest Request message instead.

But I cannot see how to create FulfillSalesOrderRequest as it seems it's part of CRM SDK library and not XRM library.

How to solve this?

Thanks in advance.
