Need to get REST/SOAP webservice for updating columns 'Primary Project Role' and 'Resource Type'

Summary:

I need 'Resource Type' and 'Primary Project Role' which are present on 'Setup an

d Maintainence>Manage Project Enterprises' screen in GET or POST API, in order to update these values in Fusion using API calls. But there is no GET or POST Rest API for such, as well as the SOAP API provided by Oracle contains these two fields in read only call. Create and Update functions of the SOAP API provided by Oracle doesn't contain these two fields. In such case, we want to know the way to update these values using API. I have mentioned below the available API URL which is present on Oracle Metalink. Kindly help us here.
