I already have the cost of different products in different periods:
- Rows: Product types
- Columns: Years
- Measures: Cost of all products
Additionally I have a information about purchasing date of all products.
I want to see the cost development of each product in relation to its age. What exactly should I do to create a field so that one can see:
"product A, which had cost of €€€ in 2016, was 4 years old at that time" ?
