Woocomerce – Update max quantity for product variation – Woocommerce

I’m trying to update max quantity for all variations of my variable product to ie 345.

$available_variations = $product->get_available_variations();


foreach ($available_variations as $variation) 
{ 
$variation_ID = $variation->ID;
update_post_meta( $variation_ID , 'max_qty', 345 );

}

It doesn’t happen.

    You are not using the correct way to get the variation ID and the product meta key max_qty doesn’t exist in WooCommerce database on wp_postmeta table for product_variation post type.

    Instead you can use the following filter hook to set a specific maximum quantity to product variations:

    add_filter( 'woocommerce_available_variation', 'wc_available_variation_max_qty', 10, 3 );
function wc_available_variation_max_qty( $data, $product, $variation ) {
    $data['max_qty'] = 345;

    return $data;
}

    Code goes in functions.php file of your active child theme (or active theme). Tested and work.
