hi Merlin

1. tax rate – it seems to be a bug.
Could you edit file \classes\core\class-wc-order-export-data-extractor.php
replace line
$row[ $field ] = ( $subtotal_amount > 0 ) ? round( 100 * $subtotal_tax / $subtotal_amount, 2 ) : 0;
with line
$row[ $field ] = ( $subtotal_amount <> 0 ) ? round( 100 * $subtotal_tax / $subtotal_amount, 2 ) : 0;

2. invoice number.
Woocommerce creates child order for each refund.
So refund should pull value from parent/main order.
Can you upload your settings to helpdesk ? Use tab “Tools” to get them.

thanks, Alex

Hello Alex,

1. Replacing the lines works fine. Now i get the tax rate for refunds.

2. I have send my settings via Helpdesk for the invoice numbers.

Thanks,
Merlin

Your solution you send me works fine!

Thanks a lot!

here is tweaked code to get invoice numbers from woocommerce germanized

add_filter('woe_get_order_value_germanized_invoice_numbers', function ($value,$order, $field) {
if( $order->post->post_type == "shop_order_refund")
    $invoices = wc_gzdp_get_invoices_by_order( wc_get_order( $order->get_parent_id() ) );
else
    $invoices = wc_gzdp_get_invoices_by_order( $order );
    if( $invoices ) {
        $numbers = array();
        foreach ( $invoices as $id => $invoice ) {
            $numbers[] = $invoice->get_title();
        }
        $value = join(", ", $numbers);
    }
    return $value;
}, 10, 3);
