Report builder - how to create rows based on other rows
I'm not sure if the name of this post is descriptive enough, but I'll try to describe my problem better here. I've been working with Report builder for 2 days, so please be kind if my question is stupid.
I have a table where I have multiple columns with data(numbers) and one column based on which I'm summing those numbers. Something like this:
Now, what I need is: for some countries I need rows which would be basically the same country name, but with some kind of % values. So it would be named something like "US[%]" and "Germany[%]" For those rows I need to calculate the values. Calculation might be something like this: (Data_column_x for US)/(Data_column_x for Germany) or (Data_column_x for India)/(Data_column_x for Germany). So there would be always Germany data involved in the calculations, cause it's percentage Germany data.
There are 2 problems here: How to create those rows, which would be based on already existing row names, so basically duplicating certain row names with addition of some sort of "flag" (e.g. [%]). And another one is how to get data for one specific country so I can use it in my calculations for those rows.
My amateur idea was to create new dataset with data only for that one country which I need in those calculations, but I was not able to combine 2 datasets in one table.
