You could probably build something like this with five calculated fields but it seems like using measure names as a filter would make more sense. 

Calc 1

CASE  [Measures]

WHEN 'All' THEN

[Sales]

WHEN 'Sales' THEN

[Sales]

END

Calc 2

CASE [Measures]

WHEN 'All' THEN [Profit]

WHEN 'Profit' then [Profit]

END

Using Measure names provides a cleaner look

Brilliant answer by ivan.yong

I was thinking of a different way-

CASE [Parameter]

WHEN 'All'

THEN

          [Measure1] + '|' + [Measure2] + '|' + [Measure3] + '|' + [Measure4] + '|' + [MeasureN]     /* using | as delimiter */

END

and then seperating the measures by spliting from delimiters. If a single meaure was choosen remaining fields would automatically stay Null.

Very Interesting, I think you will need to convert you measures to STR in order to avoid type mismatch when adding your delimiter.  Then convert back to a number after splitting if you want to aggregate.  Too much work for me, but if you mock something up please share.  I would pursue a measure names single select dropdown first as it seems clean and easy.
