Functions typically used in action rules

There are also several functions that are used in existing rules. Remember that a function used in a rule is identified by its parentheses and must return a LOGICAL value:

canNavigate() — This LOGICAL function determines whether the user should be free to navigate to another record in the dataset (whether by pressing a Navigation button or selecting a record in a browser). The function returns No if an update is in progress and unsaved anywhere within the chain of dependent data objects.
hasActiveAudit() — This LOGICAL function returns TRUE if the current record has one or more active audit records associated with it.
hasActiveComment() — This LOGICAL function returns TRUE if the current record has one or more active comment records associated with it.
