Hello Kanishk
Yes. You can work as MDG functional consultant. But its better to know technical details which helps you to know the system. As a functional consultant you are responsible for -
1. Design end to end governance process
2. Set up the approval process
3. Data modelling
4. Process modelling
5. Set up replication model with help from technical
6. End to end system testing
7. Data load setup and actual data load
These are some of the key areas where you can work but the scope is huge for functional too as you are responsible to get the system up and live....
