Verify the Updated Accounts

Check the Updated Field

Now let’s make sure that the code you executed made the changes you want. Find an older account, and check the description field to see if it was updated.

1. In your Trailhead Playground, click the App Launcher  and select Sales under All Apps.
2. Click the Accounts tab.
3. Click Recently Viewed to show the list of views, and then select All Accounts. 
4. Click the gear icon  and select Select Fields to Display. Move Last Modified Date to the Visible Fields column, and then click Save.
5. Click one of the five most recently modified account records (use the Last Modified Date to find these accounts).
6. Click Details.
7. Look for the Description field. The value should be: Heritage Account
