When you use two transfer orders for handling the rental, in this example, I already shipped the item, you should post the arrival on the outgoing transfer order when it actually arrives.
This is what happens in the video
Meaning if you look at the outbound transfer order here, I have posted it on, we have quantity shipped one and the quantity to receive one and the shipment date was September 7, on the first line.
In real life, you should post the receipt of that transfer order when it actually lands on the ramp.
And thereby, you can control if the customer received the item, maybe it has a shipment time of two days before it actually reach the customer.
And therefore, you can control that in those two days, the item is actually on the transit location.
So once it arrive on the customer side, you could receive it on the correct day. And that will give you some very nice history on your rental items.
