Open apps and app files across scopes in ServiceNow Studio
In ServiceNow Studio, you can open and edit apps and app files in any scope, global or custom. The scope that an app is associated with displays at the bottom of the screen and updates automatically when you switch to an app in a different scope.
When you open any app or file in ServiceNow Studio, it may open in an integrated tab. Each tab shows information about the file, including file name, file type, and scope.
Depending on the width of your browser screen, you may see an overflow tab appear for apps or files you've opened. From the more actions icon, select Show Opened Editors to show a list of all the opened files. Select any file to open it in the canvas.
You can also see the scope and update set associated with each file at the bottom of the screen. Switch update sets here or create one to package your changes.
