SNOW-CSA Application Rules, ACL and Notifications Practice Question
An administrator creates a new ACL for the 'incident' table with type 'record', operation 'read', condition script 'current.assignment_group == gs.getUser().getMyGroups()', and requires role 'snc_internal'. A user with role 'snc_internal' who is a member of group 'Service Desk' can view incidents assigned to 'Service Desk' but cannot view incidents assigned to 'Network Support'. What is the most likely reason?
⚠ Common exam trap
The trap here is that candidates focus on the syntax error in the condition script (options A and B) and overlook the ACL evaluation order, which is a more fundamental concept in ServiceNow that explains why the user can see some incidents but not others despite the flawed condition.
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
✓
Another ACL with higher order denies read access to all incidents not matching the condition.
ACLs in ServiceNow are evaluated in order of their 'order' field, and the first matching ACL (either allowing or denying access) determines the outcome. If another ACL with a higher order (lower numeric value) denies read access to incidents not matching the condition, that deny rule will take precedence over the new ACL, preventing the user from viewing incidents assigned to 'Network Support' even though the new ACL would allow it. The user's role and group membership are satisfied, so the issue lies in ACL ordering and a conflicting deny rule.
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 condition script uses 'current.assignment_group' which returns a sys_id, but 'gs.getUser().getMyGroups()' returns a list of group names.
Why it's wrong here
Both return sys_ids; the comparison works.
- ✗
The condition script should use 'current.assignment_group.isOneOf(gs.getUser().getMyGroups())' instead.
Why it's wrong here
The given comparison is valid.
- ✗
The user does not have the 'snc_internal' role.
Why it's wrong here
The user has the role as stated.
- ✓
Another ACL with higher order denies read access to all incidents not matching the condition.
Why this is correct
ACL order matters; a deny rule could be overriding.
