How to retrieve the current ProjectBaseline？

Hi Experts,

Do you have the experience with how to get the current active baseline for a project?

I have tried to explore the repository for Project and ProjectBaseline, it seems the only key between those two object is the field BaseProjectID in the ProjectBaseline BO. But the ProjectBaseline BO does not support the QueryByElements() method. Do we have to fetch all the active baseline till the right one?

Thanks for you sharing!

Regards

Kevin
