Review and edit applications built using app generation

After app generation creates an application, review and modify it in ServiceNow Studio to verify accuracy and extend functionality.

Starting with the Australia release, app generation is being prepared for future deprecation. It will be hidden and no longer activated on new instances but will continue to be supported. Build Agent provides the latest experience for this functionality. For more information, see Build Agent.

This video shows you how to review apps created using app generation in ServiceNow Studio.

Before you begin

You must have an existing application that you created or have access to edit. The application does not need to have been created using generative AI to use the app generation skill to edit it.

Role required: now_assist_panel_user

Note:

To edit (not create) apps, assign users the delegated_developer or now_assist_panel_user role.

Procedure

1. Navigate to App Engine > ServiceNow Studio.

   To learn more about the ServiceNow Studio home page, see ServiceNow Studio.

2. Select the Now Assist icon.
   
3. In the Now Assist panel, select Update an app.
   
4. Select the app to edit.

   The apps available for editing in the Now Assist panel are custom applications you have created or to which you have access. If the application list is long, use the search box to find a specific application.

   If you have the delegated_developer or now_assist_panel_user roles but do not see the app you need, contact your App Engine admin. Ask the admin to add you to the app as a delegated developer. For more information, see Delegated development and deployment.

   To edit an application with the app generation skill, your scope must match the app scope. If your scope does not match, the app generation skill changes your scope to the app scope automatically.

5. Select Submit.
6. Describe your changes to Now Assist.
   For example:

   • Specify additional business requirements that the application must support.
   • Request a new table extended from an existing table.
   • Request an additional role or roles.
   • Add a workspace.
   • Add a flow.
   • Add columns to an existing table.

   Note:

   Now Assist might encounter issues while updating a very large app. Consider updating the app manually in ServiceNow Studio instead.
7. Preview the application and continue making changes.

   If you asked Now Assist to create a workspace or flow, the workspace or flow is generated after saving the application.

8. Select Save and open app.
9. In the Application Files tab, open, verify, and modify items as needed.
   The following optional steps provide details about how to check some common files.
10. Optional: Review the generated tables.
    1. On the Application Files tab, in the Display name column, select an existing table in your application.
       The table record opens in a new tab in Table Builder.

       Note:

       If the Now Assist panel is covering information, select the Now Assist icon to close the panel. Select the icon again to reopen the panel and continue the conversation.

       

    2. Confirm that the table is accurate and captures the correct data.
    3. Make any changes, such as the following:
       • Update table fields.
       • Edit the table and field column properties.
       • Verify that the generated choices are implemented correctly.
       • Add a column.
    4. Close the table tab.
11. Optional: Review the generated access control lists (ACLs).
    1. On the Application Files tab, in the Display name column, select an existing access control in your application.
       The ACL record opens in a new tab.

       

    2. Verify that the created ACL is accurate and requires the correct role or roles.
    3. Close the access control tab.
12. Optional: Review the generated roles.
    1. On the Application Files tab, in the Display name column, select an existing role in your application.
       The role record opens in a new tab.

       

    2. Verify that the created role and its assigned permissions accurately represent the users of your application.
    3. Close the role tab.
13. Optional: Review the generated record producers.
    1. On the Application Files tab, in the Display name column, select an existing record producer in your application.
       The record producer record opens in a new tab.
    2. Review and modify the record producer if necessary.

       For example, select Questions, hover over a specific question, and select the Edit icon. Confirm that the question type and options are correct. Make any changes as needed.

       For more information about record producers, see Record Producer.

    3. Close the record producer tab.
14. Optional: Review a generated workspace.
    1. On the Application Files tab, in the Display name column, select the entry with a Class of UX Application.

       

       The workspace opens in UI Builder in a new tab.

    2. On the UI Builder tab, select Home to preview the workspace landing page.

       

    3. Review the workspace and, after confirming that you're in the correct application scope, modify the workspace if necessary.

       For example, add additional column layouts containing more charts and graphs.

       To see the workspace from an end-user perspective, select Preview.

       For more information about UI Builder, see UI Builder.

    4. Close the UI Builder tab.
15. Optional: Review a generated flow.
    1. On the Application Files tab, in the Display name column, select the flow entry with a Class of Flow.

       

       The flow opens in Workflow Studio in a new tab.

       

    2. Review the flow and modify it if necessary.

       For example, add or change triggers, actions, or subflows.

       For more information about using Workflow Studio, see Exploring flows.

    3. Close the Workflow Studio tab.

What to do next

Continue opening, verifying, and modifying items in the application files list as needed. For more information, see ServiceNow Studio.
