while doing sales order the material is not available some times at that time we give the delivery date when ever we expect goods. if the goods available earlier than delivery date we can go back with sales order and deliver the goods before first delivery date. this process called as backorder processing.(movement type is 562)

Backorder Processing

Backorder processing is a functionality in SAP where you can change the committments and over-ride the blockage of stocks

marked against sales documents/deliveries. For e.g. you receive an order from a very important customer for material "A" but

the entire quantity of A is committed to another customer "B" via earlier sales orders and this is where BACKORDER processing helps you to change the committment and shift stock due for B to A. This is the benefit of this funtionality.

Using backorder processing, you can list sales documents relevant for requirements for particular materials and confirm them manually. You can assign available-to-promise (ATP) stock to outstanding order quantities. In addition, you can withdraw already confirmed quantities and reassign them to different items.

Backorder processing is only available for materials with individual requirements. Summarized requirements are usually used for materials sold in bulk quantities. Backorders for bulk products are not, as a rule, processed manually.

Backorder processing from the selection list always takes place by material. This means that if you select several materials in the list, the system processes each one in turn.

If you want to reschedule in order to update the sales documents before you process the backorders, note that this may adversely affect system performance. Whenever possible, carry out rescheduling in the background.

To process backorders with a selection list, proceed as follows:

Select the materials and sales documents in the selection list that you want to process and choose Edit ® Backorders.

This overview displays the requirements and received quantities, the quantity confirmed until now and the cumlated ATP (available-to-promise) quantity (the required and received quantities in stock still available for use) for each selected material, requirements/received date and MRP (materials requirements planning) element (such as the sales order). The requirements date generated by the sales document matches the material availability date.

Place your cursor on the MRP element that you wish to process and choose Edit ® Change confirmation.

Note that you can only process the MRP elements for the lines that you selected in the list for which confirmed quantities exist. The MRP elements that you can process are highlighted. Deliveries cannot be processed as backorders so the overview does not contain any confirmed quantities for them. However, the system does take the size of the delivery quantities into account when calculating the ATP quantity.

You reach the Backorder Processing: Change Confirmation screen where you can see the details of the MRP element you selected (in the Sales requirements section for sales documents). In addition to the order and item numbers and the material availability date, the following data is displayed for a sales order item:

Field

Description

Open quantity

Quantity not yet delivered

Confirmed quantity

Quantity that has been confirmed in backorder processing

Total confirmed quantity

Total quantity confirmed for the sales order items (if there is more than one schedule line for the item, this is the total of all confirmed schedule lines)

ATP quantity

Quantity available for outwards goods movements

Backward scheduling is always carried out for both delivery scheduling and transportation scheduling. If backward scheduling determines a material-availability deadline or transportation-scheduling deadline that lies in the past, the system automatically carries out forward scheduling to determine a delivery deadline that can be confirmed.

Backward Scheduling

The system first carries out backward scheduling from the requested delivery deadline:

Requested delivery deadline

./. minus transit time

-

-

---

Goods issue deadline

Goods issue deadline

./. minus loading time

-

-

---

Loading deadline

Based on the loading deadline, the system determines two further dates, the transportation planning deadline and the material availability deadline.

Loading deadline

./. minus transportation lead time

-

-

---

Transportation scheduling deadline

Loading deadline

./. minus pick/pack time

-

-

---

Material availability deadline

The earlier of these last two dates (material availability deadline and transportation scheduling deadline) determines when a schedule line becomes due for shipping.

Forward Scheduling

If backward scheduling determines a date in the past as the date on which a schedule line becomes due for shipping or if the material will not be available on the date calculated, the system automatically carries out forward scheduling to determine the earliest possible shipping deadline.
