Need Project Profile to Create Project in PS-EPS through BAPI

hi,

Problem Description :

My Web application wants to send request through XI to Project System (PS-EPS)(on SAP system) to create project in it. I want to retrieve all the project profiles available on SAP system before making such request so that i can fill parameters in the request message by using a project profile at my Web APP end.

Is there any BAPI available which retrieves all project profiles? Tell me any alternative course of action.

Thanks in advance.
