cancel Inbound delivery

Hi,

We've posted a GR for Inbound Delivery for the false scheduling agreement.

Now we want to cancel this GR for Inbound Delivery and delete the old scheduling agreement.

Problem: Material was with HU. We couldn't cancel the GR because of HU

We've delete the HU. Now We get the Error "HU could no be found"

How can we resolve the case (cancel the GR and delete the scheduling agreement).

Thanks
