Rolling quarters/months

[florian890]

Dear all,

making progress thanks to all your great support, lot of stuff I am now able to do - and a bit more, thank you!

Today though I reached my limits once again 🙂

I have a list of

a) Customer

b) Months

c) Quater

d) Year

e) Revenue

Now I am tasked to display in rolling 4 quarters/vendor (or rolling 12 months/vendor)

Probably easy?

Thanks again for your brain-time,

Florian
