SNOW-CAD Core Application Development Practice Question

Exhibit

Refer to the exhibit.

Exhibit (Business Rule script):
```javascript
(function executeRule(current, previous /*null when async*/) {
    if (current.state == 1 && previous.state == 2) {
        gs.addErrorMessage('State change is not allowed');
        current.setAbortAction(true);
    }
})(current, previous);
```

What happens when a user changes the state from '2' to '1' on an incident record?

⚠ Common exam trap

Many candidates confuse 'before' business rules with 'after' rules, mistakenly thinking that `setAbortAction` only works in 'after' rules or that a missing return statement causes the rule to be ignored.

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 record is not saved and an error message 'State change is not allowed' is displayed.

In a 'before' business rule, calling `current.setAbortAction(true)` prevents the database operation from completing and displays the error message specified in `gs.addErrorMessage()`. When the state changes from '2' to '1', the script checks for this condition and aborts the save, showing 'State change is not allowed'. This is a standard pattern for enforcing state transition restrictions in ServiceNow.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Nothing happens because the script does not have a return statement.
Why it's wrong here
The script does not need a return; setAbortAction works.
✗
The record is saved without any message because setAbortAction is ignored in 'before' rules.
Why it's wrong here
setAbortAction is valid in 'before' Business Rules.
✗
The record is saved and a message 'State change is not allowed' is shown.
Why it's wrong here
setAbortAction(true) prevents the save.
✓
The record is not saved and an error message 'State change is not allowed' is displayed.
Why this is correct
The condition matches, so the action is aborted and error shown.
