Is alternative available in back end for drush migrate-import "ID"?
We can achieve this, without using the Drush Commands 


  drush migrate-import 'ID'


After the import process, 

$migration = "Migration ID"
$migration = \Drupal::service('plugin.manager.migration')-&gt;createInstance($migration_id);
$executable = new MigrateExecutable($migration, new MigrateMessage());
$executable-&gt;import();


If you dont want to use Drush Commands, then Create the custom module and use this above command.
