How to exclude

[Spartan27215]

How do I go about doing this...

1. I have a Dollar amount as a measure

2. I have A certification as a dimension.

I want to compare the Dollars for having the certification vs not having the certification. 

The easy part is Has the Certification...

<$<Certification={'Cert A'}>} DollarAmount

The question is how to do this to get the opposite? Note the below does not work

<$<Certification={'<>Cert A'}>} DollarAmount

As below

=sum({$-<Certification={'Cert A'}>} DollarAmount)

or 

=sum({<Certification-={'Cert A'}>} DollarAmount)
