ServiceNow Service catalog

Create a clear request experience with catalog items and variables.

By Nayeem · ServiceNow Architect and Certified Technical Architect

Understand the concept

A service catalog presents requestable offerings. Catalogs and categories organise items. Variables capture answers from the requester; variable sets reuse groups of questions. Catalog UI policies adjust the question experience, while fulfilment logic determines what happens after submission.

A practical business example

Employees request a laptop by selecting a device type, delivery location and justification. The fulfilment team receives the information needed to prepare the device.

Step-by-step practice

Use a personal learning instance and suitable permissions. Record your starting configuration before changing it.

Create a practice catalog item in the intended catalog and category.
Add a small set of clearly labelled variables, choosing appropriate types.
Use a variable set only for questions reused across items. Configure any conditional display behaviour.
Preview as the intended requester, submit a test request and inspect where the answers are available during fulfilment.

Common mistakes and troubleshooting

Do not assume a hidden or read-only browser question provides security. Test server-side validation and access where sensitive information or business rules require it.

What is the difference between a variable and a table field?

A catalog variable captures an answer on the request experience. A table field is part of a record’s table schema; mapping between them needs intentional configuration.
