You use Identity Manager rules to encapsulate constants and XPRESS logic that can be reused in forms, workflows, and other configurable components in the product.
When writing rules, use the following guidelines (as applicable) to obtain optimal performance:
Use static declarations to return a constant value.
Use defvar methods to implement algorithms with temporary values for incremented values or for values that are referenced only one time.
Use putmap, setlist, or setvar methods for complex or expensive calculations whose value must be returned multiple times. Be sure to eventually set the value to <null>.
