In Appian expressions, what does ri! denote?

• A. Process variable
• B. Rule input
• C. Global constant
• D. Local variable

Answer: (B)

ri! denotes Rule Inputs. In Appian, a rule is defined with named inputs, and the values passed to those inputs when the rule runs are read inside the rule using ri! followed by the input’s name. This makes the rule parameterized and reusable. For example, if a rule accepts an input called amount, you would access its value with ri!amount inside the rule. This is different from process variables (pv!) which reside in a running process, or from global constants and local variables used in other parts of the application.
