The extension can also trigger a partial reload process. To take full advantage of a partial reload, you need to write data LOAD commands with the prefix ADD or REPLACE.

When a partial reload runs, it only executes the LOAD statements with these prefixes and keeps the data for the remaining tables in the memory.

If you are developing in a server environment, look in the security constraints applied to the users with access to the app. Check with the Qlik Sense Administrator to grant the correct privileges for a user to reload an app within the extension.
