question about set analysis

[#1]

I have two set analysis as below:

sum({$<DivisionName = {"*"}>} LineSalesAmount) means 'All Divisions selected'

sum({$<DivisionName = >} LineSalesAmount) means 'No Divisions selected'

The results is SAME. WHY?

[rwunderlich · Accepted solution]

<DivisionName = >

means "no selection in DivisionName". Which is effectively the same as selecting all DivisionName.
