- A
The business rule is set to run on every update, but the script does not check the previous state
Why wrong: Incorrect. The method current.state.changes() correctly detects state changes. The problem is not about checking the previous state.
- B
The business rule's condition field is set to 'state changes'
Why wrong: Incorrect. Setting the condition to 'state changes' would limit execution to state changes, not cause duplicates.
- C
The business rule runs on both insert and update
Why wrong: Incorrect. This would cause an extra email on insert, not multiple emails during a single update.
- D
The email notification is triggered by a different business rule
Correct. Another business rule might also be sending an email on state change, leading to duplicate notifications.
- E
The business rule is set to run on before update as well
Correct. If the rule runs on both before and after update, it fires twice for the same update, resulting in duplicate emails.
Preventing Duplicate Email Notifications
This SNOW-CAD practice question tests your understanding of automating application logic with business rules and scripts. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: business Rules. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A developer is writing a business rule that should run on after update of the Incident table to send an email notification when the state changes. The developer uses the method current.state.changes() to detect the change. However, the email is sent multiple times for the same incident update. What are two possible reasons? (Choose two.)

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
The email notification is triggered by a different business rule
Duplicate emails on the same incident update occur when multiple business rules send the notification or when the same rule runs multiple times. Option D is correct: another business rule may also be configured to send an email on state change, causing duplicates. Option E is correct: if the business rule runs on both before and after update, it will execute twice for the same update, sending two emails. Option C is incorrect because running on insert causes an additional email on insert, not multiple emails during a single update operation. Option A is incorrect because current.state.changes() properly detects state changes; the issue is not about checking the previous state. Option B is incorrect because setting the condition field to 'state changes' would actually help filter, not cause duplicates.
