Dot Walking is a ServiceNow feature that allows you to access and include data from related tables when creating reports, conditions, scripts, and business rules.
How Dot Walking Works:
When working with records, each table has fields that may reference another table (e.g., an Incident record has an "Opened by" field that references the User table).
Dot Walking allows you to traverse these relationships by using a dot (.) notation to pull in data from related tables.
Example: If you want to include the email address of the user who created an incident, you can reference it as:
CopyEdit
incident.opened_by.email
This is useful for reporting when you need to include data from multiple related tables without needing custom joins.
Why the other options are incorrect:
A . SQL → Incorrect. ServiceNow does not use direct SQL queries for reports. It relies on GlideRecord and Dot Walking instead.
C . Outer Join → Incorrect. ServiceNow does not provide traditional SQL joins for reports. Instead, it uses Dot Walking and Database Views.
D . Joins → Incorrect. While Database Views allow for joins, Dot Walking is the primary method used to include related table data in reports.
