Woocommerce – remove sale price field from dashboard [closed]

You cannot remove the field using a code but you can disable using the sale price across the store.

To disable sale price

function custom_wc_get_sale_price( $sale_price, $product ) {
return $product->get_regular_price(); 
    return $sale_price;
}
add_filter( 'woocommerce_get_sale_price', 'custom_wc_get_sale_price', 50, 2 );
add_filter( 'woocommerce_get_price', 'custom_wc_get_sale_price', 50, 2 );

To hide this field, you can use a CSS to hide it from Product Edit screen. But that CSS needs to be loaded on the admin side, so putting this in theme style sheet may not work.
