SNOW-CSA Application Rules, ACL and Notifications Practice Question
Exhibit
(function evaluateRule(current, user) {
if (current.caller_id == user.sys_id) {
return true;
}
return false;
})(current, user);Refer to the exhibit. This ACL is applied to the Incident table for 'write' operation. A user is editing their own incident but is still denied. What is the issue?
⚠ Common exam trap
A common mix-up: candidates assume a single ACL's result determines access, but ServiceNow evaluates all matching ACLs in order, and a 'false' from any ACL (unless overridden) will deny the operation, even if another ACL returns 'true'.

Correct answer & explanation
✓
The script returns true but another ACL denies.
When an ACL is applied to a table for 'write' operations, multiple ACLs can evaluate the same operation. Even if one ACL (the one shown) returns true, another ACL on the same table for the same operation may return false, causing the overall write to be denied. The exhibit shows a script that checks `current.caller_id == gs.getUserID()`, which should allow the user to edit their own incident, but another ACL with a higher order or a different condition is blocking the write.
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 script returns false because current.caller_id is not the user's sys_id.
Why it's wrong here
For the user's own incident, caller_id should match.
- ✗
The ACL is set to 'read' instead of 'write'.
Why it's wrong here
The ACL is configured for write operation.
- ✗
The user does not have the necessary role.
Why it's wrong here
No role is required as the script allows access.
- ✓
The script returns true but another ACL denies.
Why this is correct
A more specific ACL can override this one.
