Invalid Populations

There are certain Populations you will not be able to create, these are largely negative cases. For Example looking for all of the people who didn’t do an event. We consider these cases too generalized, you will need to add a positive condition so you can run your populations.

AND operator, and ALL of its operands are negative.

You cannot create a population in which all operands are negative, this includes:

Has Not Done Event

Does not have Property

18241824

To use the population you will have to use at least one positive operand.
