SNOW-CAD Practice Question: Automating application logic with business rules and scripts
Exhibit
Refer to the exhibit. Business rule on Incident table: Name: Set Assignment Group When: before Condition: current.caller_id.changes() || current.short_description.changes() Script: current.assignment_group = 'IT Support';
What is the effect of this business rule?
⚠ Common exam trap
It's easy for candidates to confuse the condition logic (thinking 'changes to caller OR short description' means both must change) or assume reference fields cannot be set by business rules, leading them to pick option A or B.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It sets assignment_group to 'IT Support' every time the caller or short description changes.
The business rule is configured to trigger 'on change' for both the 'caller' and 'short description' fields. When either field changes, the rule sets the 'assignment_group' field to 'IT Support'. This is a typical use of a business rule to automatically assign incidents based on field updates.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It will cause an error because assignment_group is a reference field.
Why it's wrong here
Incorrect; reference fields can be set with a display value.
- ✗
It only runs when both caller and short description change.
Why it's wrong here
Incorrect; the condition uses OR, not AND.
- ✓
It sets assignment_group to 'IT Support' every time the caller or short description changes.
Why this is correct
Correct; the condition OR means either change triggers the script.
- ✗
It only sets assignment_group when the incident is first created.
Why it's wrong here
Incorrect; the condition includes changes, not just insert.
