How does decision builder handle empty inputs?

I am building a decision matrix with three inputs but some rules do not reference all three values. If I leave an input empty in the rules subtable, how does the platform handle the value? Is it disregarded or does the system find a match on the rule only where the value is null or false (in case of T/F)?

Ex: Input is T/F Flag “Select for Review”. I leave that input value blank for a rule. Will it find a match only where that flag is false or not reference the input at all when looking for a match (aka match could be found on true or false as long as all other criteria on the rule is matched)

Hey Jess, when you leave an input expression blank for a decision rule, that input is ignored entirely for that rule. The rule will match whether the input field is true or false, as long as all the other criteria on the rule “match”.

Along the same lines, it is a common pattern to have one “catch all” rule on certain Decision records that has entirely blank input expressions. In that instance, if no other rules “match”, the final one always will.

Awesome, thanks Alex! Would it be possible to have that added to help text? @Kailey

@alex.solorio did I reword this okay/keep the meaning? @jess I added this to the decision rule expressions topic.
