SNOW-CAD Practice Question: Automating application logic with business rules and scripts
What is the purpose of using the 'Async' option in a business rule?
Answer choices
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
✓
To run the rule in a separate background thread to avoid performance impact.
The 'Async' option in a business rule causes the rule to execute in a separate background thread after the database operation, which avoids performance impact on the main transaction. Therefore, option D is correct. Option A is incorrect because running immediately is the default synchronous behavior, not async. Option B is incorrect because 'Async' is not related to record viewing; that is controlled by the 'Display' condition. Option C is incorrect because async rules still run on updates; they just run asynchronously.

Why it's wrong here
Incorrect; that is the 'Display' option.
- ✗
To prevent the rule from running on updates.
Why it's wrong here
Incorrect; async rules can still run on updates.
