Records are automatically numbered in the order that they are added.
Also, record numbers are not updated once they are assigned.

If you want to reassign record numbers starting from "1", follow the steps below to recreate your app.

1. Create a new app by copying (duplicating) an existing app.

2. Export the record data of the source app to a CSV file.

3. Import the CSV file to the app created in Step 1.

   • If the new file import screen is enabled in the Update Options:
     Select "Record data" and then "Only add new records" when importing data.
     
   • If the new file import screen is disabled in the update options setting:

   When loading, clear the check boxes for "Record number" and "Key to bulk update".
   

   Records will be bulk copied to the new app and renumbered starting from "1".
