On a Business Rule, the When setting determines at what point the rule executes. What are the options for specifying that timing?

The 'When' field on a ServiceNow Business Rule specifies the timing of its execution relative to a database operation, with the four primary options being: 'Before' (before the database operation), 'After' (after the database operation), 'Async' (after the database operation, in a separate transaction), and 'Display' (before a record is displayed/loaded on a form).

These are not the exact, complete set of standard 'When' options; 'Prior to' is similar to 'Before', 'Synchronous' describes execution type, and 'on Update' is an operation, not a timing.

Insert, Update, Delete, and Query are the database operations (actions) that trigger a Business Rule, not the timing ('When') of its execution relative to those operations.

While 'Before' is correct, 'Synchronous' is a characteristic, not a distinct 'When' option, and 'Scheduled Job' and 'View' are not standard 'When' options for Business Rules.
