SNOW-CAD Practice Question: Automating application logic with business rules and scripts
Which THREE of the following are best practices when writing business rules? (Choose three.)
⚠ Common exam trap
Candidates often confuse GlideAggregate with GlideRecord and assume it can perform updates, or they think gs.sleep() is a harmless delay when it actually blocks the entire script execution thread.

Correct answer & explanation
✓
Set the Order field to control execution sequence
Setting the Order field on a business rule controls the sequence in which multiple business rules execute on the same table and event. This is critical when rules have dependencies, ensuring that prerequisite logic (e.g., data validation) runs before subsequent logic (e.g., field updates). Without explicit ordering, execution order is undefined and may vary between instances.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Set the Order field to control execution sequence
Why this is correct
Order ensures business rules run in the desired sequence.
- ✓
Use condition scripts to keep scripts clean
Why this is correct
Condition scripts improve maintainability.
- ✗
Use gs.sleep() to wait for other processes
Why it's wrong here
gs.sleep() is not recommended as it blocks the thread.
- ✓
Avoid long-running synchronous business rules
Why this is correct
Long-running synchronous rules can cause timeouts and poor performance.
- ✗
Use GlideAggregate for updating records
Why it's wrong here
GlideAggregate is for queries, not updates.
