Blanket Orders could have a “Delivery Schedule”.
A Delivery Schedule could consist of
- Blanket Order id
- date (today or in the future, no past dates)
- quantity to deliver
When a Delivery Schedule is not applicable, it could be empty.
The Delivery Schedule for a Sale could be entered by hand, or
entered with help of a wizard (for example constant weekly/monthly delivery, see idea from @maxx Best practice to manage delivery contracts - #4 by maxx)
It also could come in from
- a VDA4905 / VDA4984 / etc. delivery call
- other defined formatted file or interface
The import / replacement of the Delivery Schedule should be handled by specific
modules, which give the user the possibility to
- see which delivery calls were coming in
- see the difference between the previous and the new Delivery Schedule
- accept (or withdraw) the new schedule
When a new Delivery Schedule is accepted, it should replace the previous Schedule completely.
This functionality would not be part of the “Blanket Orders” module, Blanket Orders takes a Delivery Schedule as given, no matter where it comes from.
The Delivery Schedule for a Purchase could also be entered by hand or wizard,
but could later possibly come from other modules like “purchase_request”.
When creating a Sale and choosing a Position from a Blanket Order, the quantity
of the next delivery point in time could be proposed as quantity. It must be
possible to overwrite it by hand.
When there is no delivery schedule, the remaining quantity could be proposed.
It might be comfortable to be able to view the complete delivery schedule of the
Product while adding it to the Sale.
There could be a wizard to create a Sale draft from Blanket Orders for a specific customer,
containing all positions that should be delivered on or until a specific date. The Sale draft
could then be manually changed.
It might be convenient to have
- a comparison between Delivery Schedule quantities for a given date, and the corresponding Sales (= planned deliveries) for this date
and / or
- a warning mechanism, when there is no Sale position for a Delivery Schedule for a given date
It might be super convenient, but not necessary, to have this overview in a calendar style view.
