View cancelled GR or material documents with reference to PO.

Hi Guru,

I am looking a way or a table to find out the GR( material Document) that have been either reversed or cancelled. The scenario is that a PO can have two or more Line items with quantity say 800 each. For each of these 800 nos for each line items we have to do 800 GRs and 800 Material documents have to be created over the time. So if few of the material documents or GRs been cancelled, we want to see the details like date of cancellation and PO with PO line Item number etc for the material document or in other words the cancellation or reversal details of the GR.

Thanks in advance
