What is the typical use of a rule input in Appian?

• A. To pass values into a rule from a higher-level interface or integration.
• B. To store data in a CDT.
• C. To define UI components.
• D. To trigger a process model.

Answer: (A)

Rule inputs define the parameters a reusable rule expects and are used to pass values from a higher-level interface or integration into the rule so it can compute a result. This keeps the rule logic generic and reusable, since you supply the actual values at the call site rather than hardcoding them inside the rule. For example, a rule that calculates a discount can take inputs like price and discountRate; values come from the UI or from an external system and are passed into the rule to produce the result. These inputs aren’t for storing data in a CDT, aren’t used to define UI components, and don’t directly trigger a process model. In short, the typical use is to pass values into a rule from an interface or integration.
