Business Partners and PPM Integration

Hello,

We do have SAP HR Implemented and currently using PPM Partially (Portfolio and no cProjects). In next Phase we plan to use cProjects with resource planning etc. Below are

1. As HR is already in place and with Activating HR Integration (config), Any change to HR master will automatically create a Business Partner. Which works with standard activation. Is there any setting or place where i can restrict the BP Creation through employee. Basically i do not want all employees to be a BP. Any clue or help would be greatly appreciated....
2. On the side I did create Business partners through transaction "BP", but they don't show up in cProjects (while assigning resource in cProjects). Is this due to HR Integration.Any clue or help would be greatly appreciated....

Any clue why Business partner created through BP doesn't show. Advance thanks
