Multiple rows in matrix

 Hello,

I do have an issue with creating a matrix. I have to values which need to be shown in this matrix: Turnover 2016 and Turnover cumulated 2016. The values need to be shown for the year 2016 and monthly in 2 rows.

But in my case, if I add both values and for row Year and colum Month in a year, both values are shown in the same row.

What I need is Turnover 2016 and Turnover cumulated 2016 both shown in separate rows in this matrix. How can I achieve that?

example:

Thanks a lot for your help in advance
