Hi. Yes,you need inatsll "Best Practices". After this you can create a Propossal and Accets. And appear advanced project type with additional fields as risk and value drop down list. I you don't install B.P. in PPM allow a simple propossal like "Project Initiative" request. Also you can see advanced work flows for any requests. Good Luck
In the Portfolio Management User guide pages 16 and 17 you have the description of the initial attributes. Unfortunately I'dont know very much the tool, sorry. But any way, if the package is right configured, if you go to the attributes tab in the workbench it has to appear those descriptions.
