Empty criteria
Empty criteria is a configuration option when creating a rule or bind. If an event matches the condition, the rule or bind is executed.
For example, an event has the 'is empty or is in' criteria configured for the country ID: 'CA'. And, has the 'transaction > payment card > bank country' filter applied. This rule or bind will only execute when the bank country ID, related to a payment card, is null or is in Canada (CA is the country code for Canada).
Empty criteria rule or bind conditions:
- is empty: the selected value must be null.
- is not empty: the selected value must not be null.
- is empty or is in: the selected value must be null or within a specified value or range.
- is empty or is not in: the selected value must be null or not within a specified value or range.
- is empty or is in list: the selected value must empty or not in a specified value list .
- is empty or is not in list: the selected value must empty or not in a specified value list .
