We are running IFS Cloud and were attempting to find the API Projection that allows us to submit a change request for a supplier:

Supplier Management 3.4.6 Support Process:
A change request must have been entered by the supplier in the B2B solution.

SupplierInformationChangeRequestHandling.svc looks to be the correct projection to view the request but I can not seem to find the projection which can allow us to submit a request for a supplier.
