Backorder Processing (Sales Scheduling
Agreements)
You can check the availability of requirements from sales scheduling agreement items not only by using the feasibility check, but also by using the Global ATP Check (check method product availability check).
If necessary, the system can also generate partial confirmations during backorder processing in the background.
In comparison, in the feasibility check the requested quantities can either be completely confirmed (full confirmation), or not confirmed (feasibility not ok).
In interactive backorder processing, you can redistribute confirmed quantities across selected requirements.

In the confirmation profile, which you assign to sales scheduling agreement items, you can define the conditions under which a confirmation is full (compliant) or partial (deviating). Using the determination type you can define whether requested quantities have to be confirmed to the second, to the hour or to the day, in order for the system to issue a full confirmation.
The determination type that you have set in the confirmation profile determines whether you have fully or partially confirmed the requested quantities in backorder processing. The result of the check (Partial or Full Confirmation) is displayed as the Current Status of the sales scheduling agreement item.
Make the necessary settings in Customizing for the Global Available-to-Promise (Global ATP Check) under Product Availability Check.
You can use the Customer Exit APOBO010 to exclude sales scheduling agreement items with the current status Admissibility not ok from backorder processing, for example.
For more
information on backorder processing, see the SAP
Library for the Global Available-to-Promise Check (Global
ATP) under
Backorder
Processing.
If necessary make corresponding settings in Customizing for Supply Chain Planning under Delivery Schedule Processing for the Sales Scheduling Agreement in the confirmation profile (see Prerequisites for the Sales Scheduling Agreement).

A list
appears, displaying requested quantities, the old confirmation, the new
confirmation and quantity and date changes that have occurred between
requested quantities and dates and the confirmed quantities and dates (for
example
Qty Status: Partial Confirmation).

Your customer needs 100 PC per day on five days in a row.
The result of the availability check tells you that you can only meet the requirements for the first four days.
On the last date the system can only confirm 80 PC, so the customer only receives a partial confirmation.
