shop floor posting

version 6.1

i need some help understanding how SFC650 works. suppose we cut a work
order for 100 pieces and suppose somewhere along the way we lose a
couple so we are only going to get 98 pieces. if we post 98 good the
operations do not get closed and we only get 98 posted complete to
inventory leaving a balance of 2 remaining due on the work order. to
reflect that there are no more coming we change the work order qty to 98
to match the qty actually produced. but this does not 'close' the work
order and the operations are still open and show on the capacity and
dispatch reports. 

we tried to post 98 at each operation with the complete flag set to yes
with each posting. this completed each operation and removed the
remaining load associated with that operation fro the dispatch reports.
but it posted 98 to inventory at the last operation but it did not close
the work order (even though we said the last operation was complete).
the only way i can see to get the remaining balance of 2 out or mrp is
the manually close the work order also (SFC500 action 21).

is there any way to automatically close the work order using the
information posted via SFC650 when you are going to get less than the
required qty?
