SNOW-CAD Designing interfaces and user experiences Practice Question
A ServiceNow administrator is designing a new catalog item for hardware requests. The item should allow users to select a cost center from a list of available options, but only those cost centers the user is authorized to use. Which TWO approaches should the administrator use to implement this requirement?
⚠ Common exam trap
Candidates often confuse 'reference qualifier' with 'client-side filtering' and select options that use client scripts or custom population scripts, not realizing that reference qualifiers are the correct server-side mechanism for enforcing user-specific data access in catalog items.

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
✓
Create a reference field on the Cost Center table and apply a reference qualifier that filters based on the user's authorization.
A reference field on the Cost Center table with a reference qualifier can dynamically filter the available cost centers based on the current user's authorization, using a condition like 'authorized_usersLIKEjavascript:gs.getUserID()'. This approach leverages native platform capabilities without requiring client-side scripts or custom population logic, ensuring security and maintainability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Define a variable with a reference qualifier using a local variable that is populated by a catalog client script.
Why it's wrong here
Local variables cannot be used in reference qualifiers; they are not available at the time the field is rendered.
- ✗
Use a 'Select Box' variable type and populate it via a script that queries the cost center table filtering by user.
Why it's wrong here
Select Box is a choice list that cannot dynamically filter based on user authorization at runtime.
- ✓
Create a reference field on the Cost Center table and apply a reference qualifier that filters based on the user's authorization.
Why this is correct
Reference qualifiers can filter records based on user context, such as authorization.
- ✗
Use a 'Lookup Select Box' variable type and set the option list to a script that returns authorized cost centers.
Why it's wrong here
Lookup Select Box is a choice field that cannot use reference qualifiers; it uses a static list or scripted choices but not reference qualifiers.
- ✓
Use a 'List Collector' variable type and configure a reference qualifier to limit the available cost centers.
Why this is correct
List Collector supports reference qualifiers to filter selectable records.
