Hello,
here is the sample data:
| Shipping method | Year | Country | Quantity |
| Plane | 2022 | Albania | 33 |
| Plane | 2020 | Bulgaria | 45 |
| Train | 2022 | Greece | 34 |
| Train | 2021 | Greece | 20 |
| Car | 2021 | Germany | 3 |
I would like to calculate the following: sum of quantity IF the shipping method is Plane, minus sum of quantity IF the shipping method is Train. Then I'd like to group the results per Year, Country etc. so I would like to get these results by specific dimension, for Year 2022, 2021 etc
How to achieve something like this?
