delivery dates

I would like know the real meaning of the following terms, and mainly: how does SAP automatically calculate and fill these fields in from the date registered in the sales order under the field or First Date:

In the sales order:

- and First date = delivery date on site, isn't it? 10/05/2007 Requested delivery date (and First date) entered in the corresponding sales order = 10/.05.2008 (= the right one, I mean the one requested by the customer)

Delivery date automatically included in the delivery note = 09.05.2008

, delivery date received by our logistic provider through EDI = 11/05.2008

- DIvDateForGrp. 11/05/2008

- Deliv. Date 11/05/2008

- Mat.av.dt.09/05/2008

- Loading Date 09/05/2008

In the DN: 09/05/2008

- Planned GI: 09/05/2008

- Actual GI date: 09/05/2008

How system will calculate these dates.

    The System transfers the requirements of the orders to the availability controls.

    The system calculates the dates on basis of Scheduling.

    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 customeru2019s requested delivery date to determine if this date can be met.

    The transit time, loading time, and pick/pack time are subtracted from the customeru2019s 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

    By default, the system will calculate delivery dates the closest day, taking into consideration the working days of the shipping point and a rounding profile. In this case the system assumes a 24 hour work day and lead times can be entered in days up to 2 decimal points. This is referred to as daily scheduling.

    Precise scheduling calculated down to the day, hour and minute is supported. This allows the scheduling of a delivery within a single day. It is activated by maintaining the working hours for a particular shipping point.

    Backward scheduling is always carried out first. If the material availability date or transportation scheduling date is calculated to be in the past, the system must then use forward scheduling.

    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 helpful.

    hi murali

    If you feel this answer suits ur query please reward with points.

    These all the dates will be determined by the system depending on the availability check and transfer of requirment.

    in availability check forward scheduling and backward scheduliung all those work together you will delivery date.

    you can manually change according to you .

    Thanks & Regards
