You can create custom rules for your business that are composed of one or more
conditions. With the nested rules feature, you can create a rule that includes multiple
conditions and multiple rules-- including rules you have already created in your
system.
For instance, you are already using these rules:
- Rule A: no AVS match - order is set to review
- Rule B: CVN not supported by cardholder's bank - order is set to review
- Rule C: high-value orders - An order with an amount over USD 1000 - order is set to review
Using nested rules, you can create a new Rule D that references your existing rules. Rule
D specifies that if Rule A, Rule B, and Rule C all trigger, the order is set to
reject.
NOTE
Any rule that has profile scoring as a condition cannot be part of a
nested rule.
You cannot delete a rule if it is in use by another rule. If you
attempt to delete such a rule, a warning message appears.
