I'm sorry for confusing you. You don't have to change the production schedule to March. We'll arrange the business trip your schedule.("around March" means "from Feb to April")I think you have to do extra work due to "the Pilot run". So, we'd like to confirm when we should decide the plan, "Feb or April". For example,,,Week : Feb/8-Feb/13 400台(品揃え: 2/17, PO:2/24) business trip => Hamura should inform you until 1/24. (you need 2 weeks for the extra work.)I want to know each deadline.
