Challenge 1: Write a Script Include method that returns all incidents assigned to a user, grouped by priority. Challenge 2: Simulate a Before BR that prevents closing an incident if the caller is VIP and no resolution notes exist. Challenge 3: Use array flattening to get all unique callers for active incidents and log their email addresses — using only 2 queries. Challenge 4: Write an After BR that fires an event when an incident is escalated (priority changes to a lower number). Challenge 5: Build a GlideAggregate query that shows incident count by category, sorted highest to lowest. Challenge 6: Create a utility function that safely updates a record without triggering Business Rules or updating sys fields. Challenge 7: Write a function that detects infinite loop risk by checking if current and previous have the same values for key fields.
