Need Help Starting with SAP FICO Advice Welcome!

I’m planning to start learning SAP FICO and would really appreciate your advice. • Where should I begin? • What’s a good learning roadmap to follow? • Should I focus on FI or CO first? • In the next 2–3 years, which SAP modules will be most in demand?

Any tips, course suggestions, or personal experiences would be great. Thanks a lot!
