How do I view the Life Plans/Care Plans for the clients I am Case Manager for

To see the Care Plan/Life Plans of the clients you are Care Manager of, you can use the Client Group filter.

First, set up your clients in a Client Group (Engagement > People > Client Groups).

Then, when you access the Care Plans/Life Plans, select those groups in the Client Group filter drop down list:

Doing the above will limit the view of the Care Plans/Life Plans to only the client groups you selected.
