Already have Schengen visa: what documents do I need for 2nd trip?

[rituparna]

Hi,
My multiple entry Schengen visa (tourist visa) stamped from France Embassy in Kolkata, India is valid till 17-April-2017. I visited France on that visa in May 2016, now I am back in India. I am planning to visit Germany on the same visa from 04 to 15-Apr-2017.

My questions: Since I already have a valid Schengen visa:
1. Do I need to show proof of financial funds again?
2. Do I need proof of leave from work on company letterhead?

I had already shown these two documents while applying for the visa (French Embassy) last year.

Kindly clarify.
