In Shop Floor, consuming less tracked by lots components than expected
gives an 'Invalid Operation: lot/serial number needs to be specified
for a tracked product' error.
Discarding the dialog to fix the quantities makes the production order
disappear from the Shop Floor.
This because of the MO Readiness filter: as the move becomes partially
available, the reservation state goes to confirmed rather than assigned.
