In one of my modules I would like to create two different cron jobs to handle two different procedures. What I did was to use the Ultimate Cron module, and by implementing the cron api, to schedule one of my cron jobs. 

My problem is that in /admin/config/system/cron/jobs only the default from the hook\_cron appears and not from the hook\_cronapi. This is what I wrote.

```
/**
 * Implements hook_cron().
 */
function MODULENAME_cron() {
  //code
}

/**
 * Implements hook_cronapi().
 */
function MODULENAME_cronapi() {
  $items = array();

  $items['generate_excel_files'] = array(
    'title' => 'Table Excel Generate',
    'callback' => 'generate_excel_files_callback',
    'scheduler' => array(
      'name' => 'crontab',
      'crontab' => array(
        'rules' => array('0 3 * * *'),
      ),
    ),
  );

  return $items;
}

function generate_excel_files_callback(){
  //code
}

```
