Hello all together,
I would be glad if someone could give me the solution. I have read through many many post, but did not find what I was looking for.
I have a table like this and want to calculate the monthly sales by month and business unit.

| 31.03.2016 | ABC | 1.742.896 | 614.764 |
| 30.04.2016 | ABC | 2.196.541 | 453.645 |
| 31.05.2016 | ABC | 2.654.779 | 458.238 |

I guess for the most of you it´s quite simple, but at least I have no idea.
Thank you very much!
