To update or change an existing process for an app built in App Engine Studio (AES), edit it in Playbooks.

## Before you begin

Before you edit a process, you must add a process in Playbooks. For more information, see [Create a process definition](https://www.servicenow.com/docs/access?context=create-process-definition&version=yokohama&pubname=yokohama-build-workflows&ft:locale=en-US).

You can edit processes in App Engine Studio, but you must activate Playbooks for App Engine Studio and enable the Process Automation Designer for App Engine \[com.glide.pad.license\] plugin to get started.
For more information, see [Activate playbooks](https://www.servicenow.com/docs/access?context=activate-process-automation-designer&version=yokohama&pubname=yokohama-build-workflows&ft:locale=en-US).

Role required: sn_app_eng_studio.user or delegated_developer. For more information, see [Delegate developers using AES](https://servicenow-prod.fluidtopics.net/7nGx8ej0_uG1DIiyMPiwOA "Delegated development enables designated users without a system admin role to develop or deploy applications on the ServiceNow AI Platform. This enables administrators and delegated developers to work together to deliver custom applications through App Engine Studio (AES).").

## Procedure

1. Navigate to AllApp EngineApp Engine Studio.
2. From the My Apps page, open your application.
3. Next to a process, select the menu icon (![Menu icon]()) and then select Edit.'  
4. Take the appropriate actions to edit the process.
5. To save your changes, select Save.

## What to do next

Test a process to make certain it works the way you expect. For more information on testing processes, see [Test a process](https://www.servicenow.com/docs/access?context=test-process&version=yokohama&pubname=yokohama-build-workflows&ft:locale=en-US).
