We have a receipt of a subcontracting order like this:

ordered quantity: 4
pack. slip quantity: 2
delivered quantity: 2
back order quantity: 2

But in tdpur4130m000 'Maintain Back Orders' the order line does not appear.

How could this happend?

Backorder quantity should have nothing to do with subcontracting or not, so the backorderline should be present anyway. Did you check the purchase order history if somebody deleted the backorder by mistake?

Maybe the parameter is set to automatically confirm backorder, so it is not showing anymore. Have you cheked it yet ?

No, we do not confirm backorders automatically.

The last history entry of each order line has allways anegativ quantity.
Does it means that the backorder-lines are deleted?

In that case, it is a little bit confusing that the field backorder at the receipt is still <> 0.

Indeed, this is a hint that the backorderline has been deleted.

So, thanks for helping me.
