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
