# Edit a decision

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

## Before you begin

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://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/app-engine-studio/add-automation.md).

Role required: sn\_app\_eng\_studio.user or delegated\_developer. For more information, see [Delegate developers using AES](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/application-development/app-engine-studio/aes-app-dev-workflow.md).

## Procedure

1.  Navigate to **All** > **App Engine** > **App Engine Studio**.

2.  From the My Apps page, open your application.

3.  Next to a decision, select the menu icon \(\[Omitted image "menu-icon-purple.png"\] Alt text: Menu icon\) and then select **Edit**.

    \[Omitted image "modify-decision.png"\] Alt text: Decision table with menu actions 'Edit' and 'Delete' displayed.

4.  Take the appropriate actions to edit the decision.

    For more information on editing decision tables, see [Modify decision table structure in Workflow Studio](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/build-workflows/format-decision-table-in-decision-designer.md).

5.  To save your changes, select **Save**.
