SNOW-CSA Reporting, SLA and Imports Practice Question
Exhibit
Refer to the following transform map script:
(function executeTransformMap(source, target, log) {
if (!source.u_employee_id) {
return false;
}
if (target) {
target.u_department = gs.getUser().getDepartment();
}
return true;
})(source, target, log);What is the effect of this script on the import transform?
⚠ Common exam trap
Test-takers frequently assume the script sets the department for all records (including new ones) or that skipping records without an employee ID applies to both inserts and updates, when in fact the script only applies the department change to existing records being updated.
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
✓
It will skip records that have no employee ID and set department for existing records only.
The script uses `source.u_employee_id.nil()` to check if the employee ID field is empty. If it is nil, the script returns `false`, which causes the import transform to skip that record entirely (no insert or update). For records with an employee ID, the script then checks `action == 'update'` and only sets the department to the current user's department for existing records being updated. New records (action 'insert') are not affected, so the department field remains unchanged for them.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It will set the department to the current user's department for all imported records.
Why it's wrong here
The script only sets department when target exists (updates), not for new records (target is null).
- ✗
It will cause an error because the target might be null.
Why it's wrong here
The script handles null target by checking if (target) first, so no error occurs.
- ✗
It will skip records without employee ID and prevent updating department for new records.
Why it's wrong here
While it skips records without employee ID, it does update department for existing records; it does not prevent updates.
- ✓
It will skip records that have no employee ID and set department for existing records only.
Why this is correct
The return false on empty employee ID causes the row to be skipped. The department assignment only happens when target is not null (existing record).
