I recently created a partner portal and I'm now trying to figure out how to use this thing. Salesforce isn't much help and their documentation makes little sense to me.
Let's start with something basic. I want to limit my partner's exposure to our Opportunities. I want them to be able to create opportunities themselves and manage their own opportunities but I don't want them to be able to look at our org's opportunities, look at our pipeline, revenue, etc.
What combination of Profiles, Roles, Permission Sets, Sharing Rules, Page Layouts, Groups, Field Accessibility, etc. do I need to configure to make this work?
