You have reached the end of this course.
After completing it, you now know the basic aspects of the availability check: if there is sufficient cumulative ATP quantity on the requirement date of a sales order item, the material is available.
You can also interpret the results of the availability check in the sales order correctly: confirmations are documented in the sales order via confirmed schedule lines. Only confirmed schedule lines can be delivered to the customer.
You are also familiar with the need for backorder processing, and you are able to analyze the results of it: backorder processing can be used to automatically revise existing requirements with regards to the availability check. Its aim is to improve sales order confirmations by assignment or redistribution of ATP quantities.
