Illustration of difference between order intake and forecast

[Orstenpowers]

Dear all,

Hello! I am very new here and after trying a lot of internet research, "try & error" I recognize that I need some kind of support from your end...hopefully I won't bore you.

The below screenshot illustrates some business figures, the budget and the OI figures for a certain time period.

(I do not know if it is important or not, in the basis Excel file there is one column containing all values, while another column defines whwther it is a budget value or a OI value).

Now I would like to illustrate the difference (in %) between OI and budget, but I don't get managed. So for the first row, I would like to see a value of -1.16%.

How to do so???

I am looking forward to your help that is highly appreciated...

BR,
