Availability Check 5.8
5.8.2 Types of Availability Check
Now you must decide for which material you want to perform which availability
check. You can configure the availability check in the Availability check field of
the Sales: general/plant tab (see Figure 5.76).
Figure 5.76 Specifying the Availability Check for Each Material
If you don’t want to perform any check, enter “KP” in the Availability check field.
The check that I have encountered most often is the ATP check. ATP stands for
Available To Promise. This flag in the material master represents an extensive body
of rules that specify which criteria should be taken into account in your availability
check. Figure 5.77 illustrates these criteria.
The current stock situation of your material represents the starting point. In the
setting of your checking rule, you can decide to what extent a safety stock, any
existing stocks in transfer, your quality inspection stock, and your blocked stock
are to be included in the check. Then, your planned inward movements (purchase
requisitions, purchase orders, planned, and production orders) as well as outward
movements (the ones from your sales documents and the existing reservations)
are considered with regard to time. You can also specify in your checking rule for
these inward and outward movements whether they should be considered or not.
Checking rules are permanently predefined by the SAP system. You cannot create
your own rules. However, you have the option to manipulate the scope of the
check (see Figure 5.78).
