I was just trying to implement a better refund system while also keeping products in the order if I return them for legal and statistical reasons and I can't seem to be able to do this for the following reasons:
1. LineItem has a QuantityReturned which is great as I can store in there the number of returned products.

2. However that value is not used when calculating the total of the order so even if I say I sold one product and it was returned it back to me by setting QtyReturned to 1 the total of the order is the same when it should not be.

3. If I try to set the Qty to zero to mark the product removed from the order the lineitem is removed from the order.



Is there any way to fix this somehow? I badly need to keep this info without removing the product from the order.

Is there any workflow run when I do CalculateOrderTotal or something similar where I could plug in my logic to substract the value of the product somehow?



I think the Qty of a line item should be a readonly property that is calculated as QuantityRequested-QuantityReturned and use QuantityRequested as the value the user has entered and use the calculated Qty to do all the other operations.



A quick answer with some help is very welcome.



Thanks,
