Overview of this book

ServiceNow is a SaaS application that provides workflow form-based applications. It is an ideal platform for creating enterprise-level applications giving requesters and fulfillers improved visibility and access to a process. ServiceNow-based applications often replace email by providing a better way to get work done. The book steps through the main aspects of the ServiceNow platform, from the ground up. It starts by exploring the core architecture of ServiceNow, including building the right data structure. To add business logic and control data, and interactivity to user interaction, you will be shown how to code on both server and the client. You will then learn more about the power of tasks, events and notifications. The book will then focus on using web services and other mechanisms to integrate ServiceNow with other systems. Furthermore, you will learn how to secure applications and data, and understand how ServiceNow performs logging and error reporting. You will then be shown how to package your applications and changes, so they can be installed elsewhere and ways to maintain them easily. If you wish to create an alternative simple interface, then explore ways to make ServiceNow beautiful using Service Portal. By the end of the book, you will know the fundamentals of the ServiceNow platform, helping you be a better ServiceNow System Administrator or developer.

The session debuggers can be found by navigating to System Diagnostics > Session Debug. Once activated, they will continue while you are logged in and provide you with feedback until you choose to stop (by navigating to System Diagnostics > Session Debug > Disable all), log out, or your session times out.

This is critically helpful when you debug security or any other permission issues since an admin account is often treated very differently to a standard user.

Tip

You can also active debugging for a particular application scope with the following function call: gs.enableSessionScopeDebugging...
