How to enable RMCS with Contracts? What Setups to be done in RMCS?

Summary:

We have requirement to integrate Project Contracts with RMCS. I have done the Opt-in, what other setups i need to do in RMCS except to enable and the extraction start date for Fusion Contracts. My Contracts are getting stuck with SSP Error. I read somewhere to add Fusion Contracts to SSP and Memo line mapping but if someone can help me with navigation or screenshots that will help.

I also read somewhere it says Project should have Revenue and Billing plan/method attached as well. Is that the requirement and what can trigger Asset / Liability event.
