ServiceNow is a versatile and robust platform that enables organizations to streamline workflows, automate processes, and enhance overall efficiency. One vital feature that contributes to its flexibility is Update Sets. These are essentially containers that allow administrators to capture changes and customizations made within the ServiceNow platform and move them between instances. While Update Sets cover a range of configuration elements, one commonly asked question is: “Are UI Pages captured in Update Sets?” To answer this, let us delve into the finer details of how Update Sets work and the specific nuances related to UI Pages.

What Are Update Sets?

Before addressing the specific case of UI Pages, it is crucial to understand the fundamental purpose and functionality of Update Sets in ServiceNow. Update Sets serve as a mechanism to track and transfer modifications made in one environment to another. This functionality is essential during development, testing, and production processes, as it ensures consistency across ServiceNow instances.

An Update Set captures various types of changes, such as:

  • Table changes, including new fields or updates to existing ones
  • Business rules
  • UI Policies
  • Workflow designs
  • Script includes and client scripts

However, despite the wide range of items captured, not all changes are automatically included in an Update Set. This leads to the need for a closer examination of UI Pages.

What Are UI Pages in ServiceNow?

UI Pages are a critical component of the ServiceNow platform. They allow administrators and developers to design and customize web pages to deliver specific functionalities or user experiences. These pages serve as a canvas for creating custom interfaces by leveraging HTML, CSS, client-side scripting, and server-side scripting.

Common use cases for UI Pages include the development of:

  • Custom dashboards and forms
  • Self-service portals
  • Interactive features like wizards and prompts

UI Pages are indispensable when catering to unique business requirements that extend beyond the out-of-the-box capabilities of ServiceNow. Given their importance, it is equally crucial to understand their interaction with Update Sets.

Are UI Pages Captured by Update Sets?

The short answer to this question is: Yes, but with specific considerations.

UI Pages themselves are captured in Update Sets, provided they are created or modified directly within the “UI Page” application module of ServiceNow. Whenever you adjust an existing UI Page or create a new one, these changes are tracked and added to the current Update Set.

That said, there are essential caveats to keep in mind:

  • Embedded Scripts: While UI Pages are included in Update Sets, any server script logic, HTML templates, or embedded client scripts that are part of the page will also be captured. Ensure that the entire functionality is fully tested and tagged to the correct Update Set.
  • Custom Dependencies: If your UI Page relies on additional assets, such as custom images, tables, or related configurations, these are not automatically included in the Update Set. You will need to ensure they are captured separately.
  • Global Scope or Scoped Applications: If your UI Page exists in a specific application scope, ensure the Update Set aligns with the intended scope to avoid cross-scope issues during migration.

Being aware of these nuances is critical to ensuring successful migration and avoiding errors during the application loading process in the target instance.

Best Practices for Handling UI Pages in Update Sets

To streamline the management of UI Pages in Update Sets, consider the following best practices:

  • Organize Your Work: While working with Update Sets, ensure you are actively tracking the modifications and creating dedicated Update Sets for specific features or areas of development.
  • Thorough Testing: Before migrating UI Pages to a production environment, test them thoroughly in a sub-production instance. Pay close attention to dependencies and interactions with other system components.
  • Auditing Your Changes: It is a good idea to review the contents of an Update Set before promoting it. This includes verifying that all essential UI Pages and their dependent elements are captured and properly configured.

Additionally, collaborating with your team and documenting key decisions or workflows can help prevent confusion when working with multiple Update Sets or environments.

Conclusion

In summary, UI Pages are indeed captured in Update Sets within ServiceNow, but administrators and developers must remain cautious about dependencies, scope alignment, and related configurations. Understanding how Update Sets work, testing rigorously, and following best practices are paramount to avoiding migration issues and ensuring a smooth transition between environments.

By adhering to these guidelines, you can maximize the utility of ServiceNow Update Sets while confidently handling UI Pages and their associated elements, resulting in a more efficient and error-free development process.
