column() in rank in dimension

[karolina_]

I wanted to use If(aggr(rank(column(4),3),[Name])<=10,[ Name]) in table dimension, but although column(x) seems to be allowed (if I use column labled name it's underscored as incorrect) it's giving no data.

Replacing column(4) with expresion from 4th columns gives good results.

I am using qv 10 sr 5.

Am I doing something wrong or it's not allowed? If it's not allowed in v10 is it possible in v11?

Thank u in advance.
