Specific doubt - Is there any transation for this?

[dianafts_]

Hello!!

I would like to know if there is any transaction that allows me to know the orders that were left behind.
I will try to be as specific as possible.
  
Let's see something real:
 
My company has a 48-hour limit to deliver orders to the customer, that is, I place an order on February 12th, the expected delivery date is February 14th.
The system then issues an order to the warehouse for the warehouse to organize the order and place it for picking so that the carrier can pick it up and deliver it on the following day (February 13th) by February 14th, as defined.
 
But for some reason, there is a product that was supposed to be in stock on the defined days and is not, due to a delay in supply.
So when the system automatically sends it to the warehouse, this product is not mentioned and does not go on the delivery note for picking and then transportation.
 
The question is: How can I anticipate a failure on a delivery to the customer and notify the customer in advance?
Is there any way to see why or how the system itself did not send the product to the warehouse in advance? Any transaction? Or multiple transactions? Maybe I can export some files and make an excel and determinate something?
 
Please, I really need your help. My job depends on this. Any help would be amazing! I hope I was enlightening and that you understand my doubts. I'm not native English.
 
Thank you so much!!!
