Business Rule in ServiceNow

In the realm of IT Service Management (ITSM), ServiceNow stands out as a powerful platform that streamlines workflows, enhances collaboration, and boosts productivity. At the heart of ServiceNow’s capabilities lie its Business Rules, a critical component that drives automation and ensures efficient service delivery. In this blog, we delve into the significance of Business Rules in ServiceNow and explore how they contribute to organizational success.

What is business rule?

In ServiceNow, a business rule is a server-side script that runs when a record is displayed, inserted, updated, or deleted, based on the conditions defined in the rule. Business rules are a powerful tool used to automate processes, enforce policies, and maintain data integrity within the ServiceNow platform.

Types of Business Rules:

After Business Rule: A server-side script that runs after a record is inserted, updated, or deleted in the database. It can be used to perform actions based on the changes made to the record, such as sending notifications, updating related records, or logging information. Before Business Rule: A server-side script that runs before a record is inserted, updated, or deleted in the database. It can be used to modify or validate the data before it is saved, such as setting default values, enforcing mandatory fields, or checking business logic. Async Business Rule: A server-side script that runs asynchronously after a record is inserted, updated, or deleted in the database. It can be used to perform actions that do not need to be completed immediately, such as sending emails, creating tasks, or calling web service. Display Business Rule: A server-side script that runs when a record is displayed on a form or list. It can be used to customize the form behavior, such as showing or hiding fields, setting field values, or displaying messages.

Basic Components of Business Rule:

Conditions: Business Rules start with conditions that must be met for the rule to trigger. These conditions are defined using Glide Record queries, which specify the records to which the rule applies.

Script: The heart of a Business Rule is its server-side script. This script determines what actions should be taken when the conditions are met. It can modify data, display messages, log information, and more. 

Order: Business Rules can have an order field, indicating the sequence in which they should run when multiple rules are applicable to the same condition. This allows for precise control overrule execution.

What are the importance of business rule?

Automation: Business Rules automate repetitive tasks and decision-making processes. This reduces manual intervention, minimizing the risk of human errors and improving efficiency.

Data Validation: Business Rules can be used to validate data before it is saved to the database. This helps maintain data integrity and accuracy.

User Experience: By using Business Rules to customize form behavior, you can create a more user-friendly experience. For instance, you can set field values, show or hide form elements, and display informative messages based on user inputs.

Process Flow: Business Rules can guide the flow of processes by automating task assignments, approvals, and notifications. This keeps processes on track and helps meet service level agreements (SLAs).
