    Hi,

     

    Backward scheduling is the calculation of deadline dates: the arrival time at the customer site is calculated as the earliest possible goods receipt time at the customers unloading point on the requested delivery date. All four of the delivery and transportation scheduling lead times are subtracted from the customer’s requested delivery date to determine if this date can be met.

     

    The transit time, loading time, and pick/pack time are subtracted from the customer’s requested delivery date to calculate the required material availability date.

     

    The system calculates backward scheduling as follows:

     

    Requested delivery date minus transit time  = Goods issue date

    Goods issue date minus loading time = Loading date

    Loading date minus transportation lead time = Transportation scheduling date

    Loading date minus pick/pack time = Material availability date

     

    Forward scheduling is also done if no product is available on the material availability date calculated by backward scheduling. The system does an availability check to determine the first possible date when product will be available. This new material availability date forms the starting point for scheduling the remaining activities.  The loading time, pick/pack time, transit time, and transportation lead time are added to the new material availability date to calculate the confirmed delivery date.

     

    Reward points if it helps

    Hi,

     

    System first carry out backword scheduling based on Customer's requested delivery date.

    During this calculation it derives material avilability date.If this date is in past of Requested delivery date then material can jnot be confirmed.At this point it performs forword schedulling.

    Time considered during this are Pick PAck time,Transportation lead and Transportation time.

     

    Reward Points if useful
