PIR's and batch management issue, can this be solved in APO ?

Question

Hi All,
I've an issue. I honestly dont know where I can get a solution for that and thats why i will post it in mm and also pp forum.
Here is my issue.
All materials are batch managed. Each and every customer can get only certain batches and not all batches meet the requirement of a customer. Lets say I have 3 plants (plant 1, plant 2 and plant 3) and I have 3 customers ( cust1, cust2 and cust3). Lets say I get a demand for material and I create PIR's in plant 1. when I run MRP, it will generate planned orders. I convert that into purchase req and then into STO for plant 2. when plant 2 doesn't have the raw material to process into semi finished, I will create and sto from plant 2 to plant 3 to get the raw material. The reason we create sto to plant 2 initially is because it has to process something before it sends it to plant 1. so the link is from customer 1 --> plant 1 (finished goods) -- > plant 2 (semi finished) --> plant 3 (raw material).
Right from raw material it is specific to a customer. i.e. not all raw material batches from plant 3 will be accepted by customer 1.
so when the demand flows from customer 1 to plant 2, is there anywhere that I can keep track of for which customer that order is going and select raw materials based on the end customer ?
Can this be solved in APO ?

Hi sapcrs,
Your requirement is meet the solution of configuration of the following scenario.
customer 1 --> plant 1 (finished goods) -- > plant 2 (semi finished) --> plant 3 (raw material).
The conditions are
a) Raw material is batch managed
b) Keep track of order flow
Solution:- 
1) Maintain raw material as batch managed in R/3.  Suitably class and characterisitics to be developed to send the information to APO as that the RM is batch managed. 
2) The Bom of semi-fnished item at plant-2 to be maintained with raw material.  The source of supply has to be linked with plant-3.  The RM will be externally procured from plant-3 for plant-2 which is batch specific.  The Bom item will be send to APO as PPM which contain all bom and routing details.
3) Now once RM is ready at Plant-3, it will be sourced to plant-2 and at plant-2, semi-fnished item will be made with the production orders triggered from bom & routing data at plant-2
4) Now semi-finished item is ready at plant-2.  Once it is ready, it has to be sent to plant-1 for mfg FG.  This can be achieved by creating lane between plant-1 and plant-2. 
5) Through lane, semifinished item reaches plant-1 which is made at plant-2 which contains RM made at plant-3 which is batch specific.
6) Using semifinished item, Finished product can be made at plant-1
7) Now your final requirement is to track all order flow changes.  This can be achieved by mechanism in APO called pegging.  Using pegging, the order flow can be tracked right from FG to RM.
