KanBan Adjustment/Reversal? v8.03

To other KanBan using manufacturers, how have you found is the best way
to adjust a KanBan Receipt that was entered erroneously? Say someone
entered 1000 instead of 100 and we need to do a job adjustment - how
are you accomplishing this? We know we can do an adjustment to the
inventory of the item, but what about all that material and labor that
would have backflushed in error? Don't tell me the only choice is to
go in and make adjustments all the way down through the bill. Give me
your best practices. THANKS!
