material availability date

Hi Friends,

This is a question on relationship between availability check and transportation scheduling.

How does system determine material availability date when creating sales order? can you support with an example so that it could be easier to understand.

    When you create an order, the system can determine the required material availability date based on the delivery date requested by the customer. The goods to be delivered must be available for shipping at this point in time.

    Scheduling takes into account the following times:

    Transit time: Time required in order to ship a delivery to the ship-to party

    Loading time: Time required for loading the goods

    Pick/pack time: Time required for picking, packing

    Transportation lead time: Time required for organizing the transportation

    Next, the system performs backward scheduling in the order. If the result is a date in the past, the system automatically performs forward scheduling, which requires the confirmation of a new requested delivery date. The same happens if the material is not available by the material availability date.

    For example let us take transit time as 2 days; loading time as 1 day; pick pack time as 1 day;transportation lead time as 1 day.

    Customer calls and confirms an order and indicates delivery date as 20th June. Now system does backward scheduling from requested delivery date 20th June

    Requested delivery date - transit time 2 days = Goods issue date (18th June)

    Goods issue date - load time of 1 day = Loading date (17th June)

    Loading date - transportation lead time of 1 day = 16th June

    Loading date - pick/pack time of 1 day = 16 June.

    As per example above, material should be available on 16th June so that delivery can be confirmed to customer.

    If the system finds that material is not available on 16th June as per availability checks then it does forward scheduling described in manner above and projects earliest possible date for delivery.

      I am getting route determination to work and the route is coming in but the schedule line is not backwards scheduling. I have introduced a new material type and new item category at the VBAP and VBEP level. I am assuming there is some configuration somewhere that makes the schedule line relevant for transportation planning. Again the route is coming in but all dates PGI etc. equal the delivery date.

      Please advise,
