SNOW-CAD Working with Data Practice Question
A developer needs to ensure that when a Configuration Item record is deleted, all related Incident records have their CI field set to empty. Which approach should be taken?
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
✓
Create a business rule on the CI table that updates incidents on delete.
A business rule on the CI table with a 'before delete' or 'after delete' condition can query all incident records referencing the deleted CI and set the CI field to empty/null. Option A ('cascade') would delete the related incidents instead of clearing the CI field. Option B (workflow) is unnecessarily complex; a business rule is more efficient and direct. Option D (database trigger) is not supported in ServiceNow.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set the reference field's 'Delete action' to 'Cascade'.
Why it's wrong here
Cascade deletes the related incidents, which is not the requirement.

Use a workflow on the CI table to update related incidents.
Why it's wrong here
Workflows are not efficient for this simple update.
- ✓
Create a business rule on the CI table that updates incidents on delete.
Why this is correct
A before delete business rule can iterate related incidents and clear the CI field.
- ✗
Use a database trigger on the CI table.
Why it's wrong here
