Hi @wicara,

Thanks for writing in!

If you use SKUs, set the SKU or leave blank to use the product’s SKU. If you set the SKUs at the variation level, they should appear on the product page. If they’re not set, the SKU will just display as SKU: n/a.

WooCommerce Documentation:

• https://docs.woocommerce.com/document/variable-product/#draft_check_box_list_0

If you want to change the default n/a to something else, then you will need to modify the product meta. Assuming that you have your child theme active and ready, please follow these steps below:
1] Using Notepad or TextEdit or Sublime Text or any text editor, please create a new file in your local machine.
2] Insert the following code into that new file

<?php
/**
 * Single Product Meta
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/single-product/meta.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see 	    https://docs.woocommerce.com/document/template-structure/
 * @package 	WooCommerce/Templates
 * @version     3.0.0
 */

if ( ! defined( 'ABSPATH' ) ) {
	exit;
}

global $product;
?>
<div class="product_meta">

	<?php do_action( 'woocommerce_product_meta_start' ); ?>

	<?php if ( wc_product_sku_enabled() && ( $product->get_sku() || $product->is_type( 'variable' ) ) ) : ?>

		<span class="sku_wrapper"><?php esc_html_e( 'SKU:', 'woocommerce' ); ?> <span class="sku"><?php echo ( $sku = $product->get_sku() ) ? $sku : esc_html__( 'N/A', 'woocommerce' ); ?></span></span>

	<?php endif; ?>

	<?php echo wc_get_product_category_list( $product->get_id(), ', ', '<span class="posted_in">' . _n( 'Category:', 'Categories:', count( $product->get_category_ids() ), 'woocommerce' ) . ' ', '</span>' ); ?>

	<?php echo wc_get_product_tag_list( $product->get_id(), ', ', '<span class="tagged_as">' . _n( 'Tag:', 'Tags:', count( $product->get_tag_ids() ), 'woocommerce' ) . ' ', '</span>' ); ?>

	<?php do_action( 'woocommerce_product_meta_end' ); ?>

</div>

DO NOT forget to change the N/A in the code above.

3] Save the file named as meta.php
4] Upload this file to your server in the child theme’s folder wp-content/themes/x-child/woocommerce/single-product/ or wp-content/themes/pro-child/woocommerce/single-product/

You will have to create the folder path since it does not exist in your child theme yet.

Hope this helps.
