Dear Siva
At the time contract Qty of all lines items is not cleared but confirmed as in totality, but Rate of all lines is clear
So total qty of Sales orders may be  not be excess of total qty of contract but a single line item may be excess in sales order for Example
                   Contract     Sales oreder    Diff                                                     Status
Line 1    of   150 QTY     250                 Line item is excess by 100 qty             What will be shown ?
Line 2    of      100 QTY       150                        Line item is excess   by 50  qty                     What will be shown  ?
Line 3    of       250 QTY      100                        Line item is short by     150 qty                     How will be completed ?
Total Qty       500 qty            500 qty                                total impact is 0
