Flexible Planning in R/3 and Product Allocations in APO 
Purpose
You have a description here of how you carry out planning (Flexible Planning) in R/3 and how you carry out the availability check against product allocations (
product allocations) in APO. Product allocation is triggered by the sales order entry.This scenario also applies to the changeover from R/3 to APO where further planning should take place. For this, the characteristics combination and the product allocations have to be transferred from the
product allocation group to the planning area. For further information see product allocations in the sales order entry.Prerequisites
In Customizing for Sales and Distribution choose Basic Functions ® Availability Check and Transfer of Requirements ® Availability Check ® Availability Check Against Product Allocation ® Define Flow According to Requirement Category.
In Customizing for Sales and Distribution choose Basic Functions ® Availability Check and Transfer of Requirements ® Availability Check ® Availability Check Against Product Allocation ® Process Flow for each Schedule Line Category.
For further information see the R/3 Documentation: Basic Functions and Master Data in Sales and Distribution Processing.
Updating must be activated for the info structure.

The incoming orders quantity in the info structure can diverge from the incoming orders quantity in APO. The cause of this is the implementation of product allocation in APO and corresponds to the design.
The prerequisite for this is the existence of a planning hierarchy.
Choose Master Data ® Planning Hierarchy ® Change. Enter the product allocation object and the characteristics in the dialog box.
Choose Master Data ® Proportion Calculation ® Planning Hierarchy Basis.
For further information see the documentation LO – Sales and Operations Planning (SOP).
As of 4.5B, product allocation quantities are transferred from Flexible Planning via Environment ® APO Transfer. This can then only be carried out using transaction CIF.
As of 4.6C you can transfer the product allocation quantities and the product allocation control via Logistics ® Central Functions ® Supply Chain Planning Interface ® Core Interface Advanced Planner and Optimizer ® Environment ® Product Allocations and Product Allocation Control.
Example
The product allocation process can be explained using the following example. Product is P, requirements quantity is 3001, check methods are product availability check first, then product allocations.
