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

## Before you begin

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).").

Add logic and automation to your application. If you created an application using a template, logic and automation may already be added to your application. For more information on adding custom logic and
automation, see [Add logic and automation](https://servicenow-prod.fluidtopics.net/rM8ysRie1MDs7erpPUQeWA "Replace manual work by adding logic and automation to your app in 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 flow, select the menu icon (![Menu icon]()) and then select Edit.  
   Figure 1. Edit a flow  
   Note:  
   When a flow is triggered by a record being created or updated in a data table, it's referred to as a record-based flow. Record-based flows display in the list of logic and automation with a distinct icon (![Record-based flow.]()). These flows open up within the Flows tab in Table Builder if you are licensed for Table Builder for App Engine and have it installed. Contact your account team for details. For more information on flows functionality in Table Builder, see [Flows in Table Builder](https://servicenow-prod.fluidtopics.net/rYu4JOIBDCwZwTb3YSdJ9w#flows-tb "You can use the Workflow Studio functionality that is integrated within Table Builder to manage your table's record-based flows. You can manage these flows by using the Flows tab.").
4. Take the appropriate actions to edit the flow.

   | Option | Description |
   | Change the flow name, description, or roles | In the main header, select Properties, enter the values you want into the appropriate fields, and then select Update. |
   | To edit the trigger | In your flow, select the trigger description, fill in the fields as desired, and then select Done. Note: Modifying triggers can result in the deletion of referenced action configurations. |
   | To edit an existing action | In your flow, select the action description, fill in the fields as desired, and then select Done. |
   | To add a new action | In your flow, select the plus icon in the ACTION section, then proceed as you would for adding an action to a new flow. |

## What to do next

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