can't perform RMA receipt from Depot repair after upgrading from 12.0.6 to 12.2.4

Hi all,

We are currently in a process of upgrading from 12.0.6 to 12.2.4.

All of our Items which we handle in Depot Repair are Serial controlled and Tracked in Install Base...

When I tried to receive back a damaged product from Repair Order ( Service Order) , I can't do it - not from pre-upgrade existing Repair Order and not from new post-upgrade Service Order.

The problem which occur is:

Go to Logistics TAB --> stand on Return line --> choose Recieve action and press Go button --> pass 'Find Expected Receipts' form and 'Receipt Header' form and 'Receipts' form

--> now on 'Lot Entry' form I entered the returned Lot_Number and press TAB and the Quantity field is
