Landed Cost

Hi

i did landed cost setup and created Purchase order Landed cost applied in order.

But i did voucher match but with match type 2 line is not appearing in F43121 in landed cost setup i have made the voucher flag 'Y' still not appearing.

and for Receive i can see 2 lines in F43121 so how we calculate amount received .

for example for order amount paid to date is blank Amount open is 20000 for Received and 2000 for landed cost and amount Received is also same as Open . so it will be calculated as 22000 which needs to be paid or received.?
