Let's first try to understand what is a related list in ServiceNow according to ServiceNow docs. Related list: Defined related lists provide a list of any records you want at the bottom of the form. For example, a simple defined related list that lists other rooms on the same floor may be placed on the Room form. This helps you quickly navigate between them. To create a defined related list, we'll need to use a little JavaScript. We'll work through this in more detail in Chapter 3, Server-Side Control.

Before you begin Role required: admin About this task For example, you may include a list of related incidents at the bottom of a problem record, or a list of members at the bottom of a group record. This functionality depends on reference fields or many-to-many table relationships. If two tables are related via the system dictionary, one can appear as a related list on the other. Defined related lists allow relationships between arbitrary tables to be expressed as a related list. Any two tables that can have a logical relationship can appear as a parent/child pair via a related list. The following are some examples. On an incident record, show all incidents opened by the same caller. On a user record, show the last 20 transactions that the user has made. On an incident record, show all problems opened on the reported CI. These relationships are beyond the relationships normally defined in the system dictionary through reference fields and many-to-many relationships. Every related list requires a relationship record. Before creating a relationship, verify that there is not an existing relationship record that already provides the needed information. Use the following steps to create a relationship record. Procedure: Click System Definition -- Relationships. Click New. Specify the relationship record fields. Click Submit. A related list on a form serves the purpose of providing additional information related to the form record and gives a quick overview of how the other records would be affected if something is modified in the current form record. Also, it provides ease of creating new records or adding existing records, based on the permissions available to the user, from the child table for the parent one. Here based on the related lists, you can easily tell that this user is an end-user since there is no role associated with the user, has a single group membership, and has an asset assigned.
