Hello Russ Schneider,

I don't know why you are going for a deleting option. In my opinion that is not a good strategy. also Odoo does not support this, from my understanding.

This is what I think is better,

Instead of Deleting, Cancel that order.

Scenario:

Receive only what the Vendor has sent you.

Then don't create backorder. If you select NO Backorder option, It will go to cancel state.

By this, you will get full tracking of your order cycle.

Edited:

Scenario:

Step 1: You can receive it. That only what the vendor has sent you.

Step 2: There are items that aren't shipped and you create a Backorder for those. But you did not validate that Backorder at that time.


Step 3: Eventually, you wish to remove a line item from the backorder because you no longer expect/want to receive it.

Step 4: Then take that Backorder you created. and receive only that vendor send you. (i.e: deduct the quantities that you are not expecting).

Step 5: This time also. It asks for Creating Backorder or No Backorder at the time of validating the already created Backorder(2nd step).

Step 6: Select the option NO Backorder now.

Step 7: As a result, non-expecting products will be going to the cancel state.



Note: I started the previous answer from the 4th step of the edited answer, I think maybe that is why you guys confused. We have the option to create Backorder again for Backorders. I could not find any problem in this scenario. 

Correct me if I am wrong. Maybe I was taken the question from a different perspective. Kindly expecting your advice.

Thanks & Regards
