PO at 400-400 status even after complete reversal of receipt.

Hi Guys,

We have a PO which has 5 lines. we reversed the receipt and status of all the lines moved to 999-400 (L-N) except line no 3. It Moved to status 400-400. Previously, all other lines except for line no. 3 were received completely at once. The line no 3 was received in 2 rounds.

Now, after reversing all the 6 OV lines(4+2), the status of all lines except 3 are 999-400(L-N) and line no 3 has 400-400 even when we do not have anything to reverse now / anything as received. By right, the line no 3 also should be at 999-400.

Please help us to know the reason.
