GR POWL QUERY - Received Quantity field update

Hello Team,

The requirement is to create a GR Query in which business can see the GR worklist in SNC Portal. This GR worklist will output the GR quantities in SNC based on GR done against PO and IBD ( ASN) in ECC.

I have created the above QUERY and its working fine, but i got stuck at one point i.e.:

If PO created for 100 qty and ASN has been created for 30 Qty and NO GR has been done, then my worklist is displaying Received quantity as 30 Qty (ASN Qty).

But actually it should display Received Qty as 0 (ZERO) as there is no GR done in ECC.

Is there any Standard settings available wherein we can acheive the above functionality?

Thanks,

Utsav
