What types of values can be used in business rule run-time prompts?

In the context of business rule run-time prompts within EPBCS, substitution variables are specifically designed to allow dynamic input at the time the business rule is executed. They enable users to define values that can be passed into the business rules at runtime, giving users flexibility and control over how rules are applied without needing to hard-code values.

Substitution variables can reference the member dimensions set in the application, allowing for dynamic selections. For example, if a user wants to run a calculation for a specific department or business unit, a substitution variable can allow them to specify that department at the moment the rule is executed, rather than having to predefine it within the rule itself.

The other options mention various types of values that might exist in EPBCS. While strings and integers are common data types, they do not provide the same dynamic functionality as substitution variables in the context of prompting during business rule execution. Members can refer to various entities in the system but are not utilized in the same way as substitution variables to facilitate user-driven input at runtime.
