Rejected Material Valuation rate should not be 0?

We have made PO with 50 item Qty. All the items are rejected due to some reason.
While Making an GRN
Received Qty= 50
Accepted Qty = 0
Rejected Qty = 50

It works good. but in rejected Qty Valuation rate could not be fetch.

The listing states both Incoming and Valuation Rate are 0 value.

Cross check reports to diagnose where that Item rate changed from non-zero value to 0?
