Using Table Calculations for static value

[helina]

Hello! 

I am looking a way how to add specific static value using Table calculations. For example if I have article 1 static value = 14, if I have article 2, static value is 15. 

What is the best way to do that? 

Is it later possible to summarise the static values as well (e.g. based on product category)?

If(f1=“Art1”, 14)

you can nest if statements.

alternatively use a custom dimension (grouping).
