SNOW-CAD Practice Question: Automating application logic with business rules and scripts

Exhibit

function executeRule(current, previous, gs) {
    if (current.category.changes() && current.category == 'hardware') {
        current.assignment_group.setValue('hardware_group');
    }
}

Refer to the exhibit. The Business Rule is set to run on before update. When a record's category is changed to 'hardware', the assignment group is updated correctly. However, when a record is inserted with category 'hardware', the assignment group is not set. Why?

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 condition 'current.category.changes()' returns false on insert.

The condition 'current.category.changes()' checks if the category field has changed from its previous value. On insert, there is no previous value, so this condition returns false, causing the business rule to not execute the assignment group update. Option B is incorrect because the business rule does run on insert (it is configured to run on insert as well, despite the stem mentioning only 'before update'), but the condition fails. Option C is incorrect because the rule runs before the database operation. Option D is incorrect because setValue works on insert.
