A customer wants their parts on a certain date- this is the Due Date or Deliver by Date. We can set a due date for each workorder.
Now there may be delivery lead times, and default global delivery lead times can be set, as well as per customer. If we work back from the Due Date, in working days, by the delivery Lead time, we arrive at the Cut By date.
Some parts may need extra processing, and the extra processing may entail a further Extra Processing Lead Time, if this is the case we work back still further. Thus each line item in a workorder my have a different Cut By date depending on the extra processing involved.
The Schedule By date is the date you want the parts in the workorder to be nested and scheduled on to a plate for cutting.
The schedule by date is calculated in one of two ways:
1.Backward from each workorder item Cut By date by a specified number of working days.
2.Forward from the workorder created date by a specified number of working days. (Workorder is “created” at the point the workorder is first saved)
Each workorder item will have a schedule by date according to these rules. If we choose method one, items with different cut by dates will have different schedule by dates.
The overall workorder schedule by date will be the earliest item schedule by date.
Plate Cut By Date
When parts are nested on a plate, the plate gets its own Cut By date, defined as the earliest Cut By Date of any part nested onto it.
