I just found the inbound stock list, that was way easier that I thought...
But now I am trying to add a column to this list. I tried like this:
function purchase_order_filter_posts_columns( $column, $post_id ) {
// Add custom order_nummer column
if ( 'order_nummer' === $column ) {
$order_nummer = get_post_meta( $post_id, 'order_nummer', true );
}
}
I am just wondering if I am getting the right custom post type?
Best regards,
Olga
