Set Analysis with variables

[benz-ait]

Hello guys,

How can I  replace this   champs1={'string1','string2'}  in the set analysis below  by variable ?

sum({<champs1={'string1','string2'}>} champs3)

May be this

vVar

champs1={'string1','string2'}

and then this

Sum({<$(vVar)>} champs3)

Note that expression editor might show error, but ignore the error and click okay to see if you get the desired output or not.

I have this solution and it's work very well

vVar

='champs1={"string1","string2"}'

and then this

Sum({<$(=vVar)>} champs3)
