What are literal values that can be called from any expression and reused across multiple objects?

• A. Constants
• B. Groups
• C. Records
• D. Sites

Answer: (A)

Constants are named, typed values stored in one place that can be used anywhere in Appian. They represent literal values that can be referenced from any expression—whether in interfaces, process models, rules, or other objects—so the same value can be reused across the whole application. This makes maintenance easy: change the constant once, and every place that references it updates automatically. For example, a constant like DEFAULT_PAGE_SIZE = 20 can drive pagination in a UI, a data retrieval rule, and a process decision without hardcoding 20 in multiple places. Groups, records, and sites serve different purposes (security, structured data, and UI navigation), but they aren’t global literal values shared across expressions.
