Integration of SAP PS into cProjetcs

Hi,

Need help for setting up cProjects and xRPM. Scenario is as followed. As project system we use SAP PS and there are a lot of projects already defined. Now I've to set up cProjects in the way that we could see all projects that are defined in PS in cProjects. Customizing looks fine 'cause I could link WBS elements to cProjects tasks.

So my question is now: What I've to do to use my PS projects in cProjects suite. Is this possible? I don't want to define new projects in cProj.

I'm new to this topic so thx for any input and help.

Best regards,

Daniel
