Collaboration Room template path

Hi All,

Task:

To place a file in a specified folder of Collaboration Room template path.

Process

1. When i created a portfolio item in PORTFOLIO tab.

2. An External ID is created and automatically it add a path to CROOM.

3. Go to ROOMS, we can find the Portfolio item related documents here.

4. Through class /RPM/CL_ROOM_SERVICES, i found the

a) EXTERNAL_ROOM_ACCESS_URL

b) INTERNAL_ROOM_ACCESS_URL

c) ROOM_ID

d) TEMPLATE_NAME

5)And i used the web service RoomABAPWS.

Details link: http://sapsamplepro.blogspot.com/2012/01/collaboration-room-template-paths.html

Problem:

I can't able to find Room template path for portfolio item.

Doubt:

1. Is there any web service to find out.

2. Or any other ways to find the path, so that i can place a file(document) inside the folder of a particular portfolio item.

Thank you,
