Aggr based on GetCurrentSelections()

[LorenaGSaar]

Hello All,

I have one expression like : Aggr(Sum(Sales), Dimension)

And my Aggr it will depends on the filter. So if I have Product, my expression will be:

Aggr(Sum(Sales), Product)

If I have Product and Type selected, my expression must be:

Aggr(Sum(Sales), Product, Type).

How can I do it? I have tried with GetCurrentFields(), but the result is with "spaces" between each result, and even removing the '\n', I still cannot work with the result. 

Thank you all for the tips!
