Purpose
You want to carry out a combination of basic methods (for example, product availability check + product allocation). You check firstly how much of the requested product is available. The confirmation is made for the following product allocation, for example, depending on the customer.
Unlike in the R/3 System, you can define the execution sequence of the basic methods as often as required in Customizing for Global ATP.
You can carry out this advanced method in the
Simulation as well as starting, for example, from the order entry in SD (R/3).Prerequisites
You maintain the check instructions in Customizing for the Advanced Planner and Optimizer via Global ATP ® General Settings ® Maintain Check Instructions.
Example
The combination of basic methods process will be shown using the following example. You configured the combination of product availability check (as first check method) and product allocation (as second check method). You create a sales order for 1000 tonnes. The product availability check shows that 750 tonnes are available. For the June period the check against product allocations shows that only 500 can be confirmed in this checking horizon. In the following period 250 tonnes can be confirmed. There are therefore two deliveries.

Results
The sales order is created with the corresponding
schedule lines.
