Due Date – This date is the date required for dispatch to meet delivery on “Promised Date”. This date needs to factor in Transit times etc. For example with Tatua the Due Date is 42 days less than the promised date. Production should be planning to have product available before this date and this should be factored into MRP (Keeran / Jennifer, please confirm if this is the case) If production, later, advise that they can no longer meet this date the customer is to be advised and the Promised Date and Due Date amended accordingly and updated confirmation should be sent.
