Deprecated in 5.0.0. WooCommerce native COGS and common third-party plugin keys are now included by default in wpd_ai_default_product_cost_price_meta_keys. Use that filter to add, remove, or reorder meta keys instead.
To disable WooCommerce native COGS (_cogs_total_value), remove it from the default meta keys array:
add_filter( 'wpd_ai_default_product_cost_price_meta_keys', 'wpd_ai_remove_native_cogs_meta_key' );
function wpd_ai_remove_native_cogs_meta_key( $meta_keys ) {
return array_values( array_diff( $meta_keys, array( '_cogs_total_value' ) ) );
}
