Availability Check 5.8
5.8.5 Sample ATP Availability Checks
Here are four examples from SAP training documents so that you better understand
the process of the ATP availability check. The descriptions are based on the
following initial situation (see Figure 5.80).

Figure 5.80 Process of ATP Availability Check, Initial Situation
I have a stock of 100 units and two open purchase orders, the first for 50 units
and the second for 60 units. There are also three sales orders in the SAP system:
for 100 units, for 40 units, and for 50 units.
Example 1: Material is Available on the Required Date
In the first example, your customer orders 10 units. You enter this sales order with
the corresponding required delivery date. The system now calculates the availability
date based on your settings (backward scheduling, see Figure 5.81) and
performs the availability check at this time.
