Rudy says that he will check, or investigate, this backorder.

鲁迪说他会检查或调查这个延期交货。

But, before I place the new order, I wanted to check on some items we have on backorder.

但是， 在我下新订单之前，我想检查一下我们有延期交货的一些商品。

So, to have something on backorder means that you're waiting for the company to get the product so they can send it to you.

因此，延期交货意味着您正在等待公司拿到产品， 以便他们可以将其发送给您。
