Learning ServiceNow

Lists and Forms

In this chapter, we'll discover how lists in ServiceNow are similar to tables in any other relational database, and just what exactly that means for our data. We'll learn how relationships between data are created and stored in these lists, and get a brief introduction to the data-types in ServiceNow. While we're at it, we'll also learn how to either personalize or configure how list data is displayed, and edited.

As an integral part of understanding data structures in ServiceNow, we'll also learn about forms and form views, the types of data that you'll see in forms and lists, and how to personalize or configure what data shows up where.

In this chapter, you'll also learn how to create a custom table as part of the foundation for your first application: a virtual war room for major incidents. This application will be used to demonstrate various pieces of functionality...

List v2 versus List v3

Before we get into a deep discussion about tables and how they work, you should be aware that there are two common versions of the list view in use presently: List v2, and List v3. You can see if the List v3 plugin is enabled in your instance, by going to System Definition | Plugins, and searching for the term list. If it is enabled, the Status column will show Active with a little green circle. Otherwise, it'll just show Inactive.

While List v3 is the latest generation and thus, what we're going to focus on in this book, it is important to understand List v2 as well. This is because all embedded lists, list reports, and lists for tables that have hierarchical lists enabled such as the update set (sys_update_set) table list, all display in List v2 by default, since List v3 does not support those features.

A quick and easy way to tell if you're looking at a List v2 or a List...

Lists and Tables

Lists in ServiceNow can be equated strongly to tables in databases. For the most part, this would be an accurate comparison. Viewing a list, is viewing a representation of a subset of records within a table on ServiceNow's servers. The columns of that list correspond to fields within the table, and often fields which would show on the form (if configured to do so).

Each table in ServiceNow has a label (a friendly name), and a name. The label is defined in the table dictionary (something we'll discuss later in this chapter), and can contain spaces and other characters not allowed in the table's name. The name is often more difficult to remember, but more specific. The label "task" may refer to the base task table, problem tasks, catalog tasks, or a multitude or system or custom tables. However, the name sc_task makes it clear which table we're referring to (the catalog...

Forms

As you've seen, forms are where data is displayed in ServiceNow, but you wouldn't want to display every single field in your table to all of your users! For this reason, forms have views that limit which fields are shown, and to whom.

Form views can be configured, or personalized, split into sections, and can contain and display all manner of different kinds of data. Data can be made to be displayed, made read-only, or made editable in forms based on various conditions that we'll discuss in chapter 6, UI and Data Policies. In this section, we'll briefly go over how to configure and design forms, how to personalize them, and make them your own, and how to configure form sections and related lists. More details on the specific components that'll show up in forms will be covered in later chapters.

...

Summary

In this chapter, we learned about lists-both version 2 and version 3, available in the latest versions of ServiceNow-as well as tables and forms. We created custom tables, table filters, custom fields, and learned about dot-walking through Reference fields.

Lists and forms are fundamental to ServiceNow, so don't be afraid to come back and reference this chapter as you read on.

My company acquired a company that created an application that runs on ServiceNow. I needed to learn it ASAP. This book was just the ticket. It walks the reader through the ServiceNow concepts in an easy to follow manner. It also suggested the free development instance ServiceNow offers, which is invaluable to use to follow along with the book. All in all, I highly recommend this book if starting out with ServiceNow.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.
