SNOW-CSA Application Rules, ACL and Notifications Practice Question
Exhibit
Application rule (Business Rule):
Name: Set Priority
Table: incident
When: before
Order: 100
Condition: current.state == 1
Script:
gs.log('Setting priority to 1', 'test');
current.priority = 1;
current.setWorkflow(false);
ACL on incident.priority:
Name: priority.write
Type: field
Operation: write
Condition: gs.hasRole('admin')Refer to the exhibit. An incident is created with state 'New' (1). The user creating the incident has the role 'itil', not 'admin'. After the business rule runs, what is the value of the priority field?
⚠ Common exam trap
ServiceNow often tests the misconception that ACLs block all writes, including those from business rules, but the key distinction is that business rules run with system privileges and are not subject to ACL restrictions.
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
✓
The priority is set to 1 because business rules run with system user privileges.
Business rules in ServiceNow run with system user privileges by default, meaning they are not subject to ACL restrictions. Therefore, even though the user has the 'itil' role (not 'admin'), the business rule sets the priority field to 1 successfully. The ACL check only applies to direct user operations, not to server-side business rule execution.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The priority remains null because the ACL denies write for non-admin users.
Why it's wrong here
Business rules run with system user, bypassing ACLs.
- ✗
The priority is set to 1 because the business rule runs before the ACL check.
Why it's wrong here
ACLs are checked during update, but business rules with system user bypass.
- ✗
The priority is set to 1 but the update fails due to ACL.
Why it's wrong here
No failure; the update succeeds.
- ✓
The priority is set to 1 because business rules run with system user privileges.
Why this is correct
Business rules execute with system user, so ACLs are not enforced.
