How much FI knowlegde is required

Hi Gurus,

I need a theoretical and subjective answer for my question.

1- How much FI knowledge will be required for a BW consultant for a solution architect role in a bank for FI-BW analytics role?

2- What all techno-functional   areas needed to be covered inr/3 side.(extractors, table behind the extractors, delta methods etc.)

Thanks in advance
