APO 7.03 - organizational areas for batches and CDP

Hi,

I am using SAP ECC 6.0 with APO 7.03. We use shelf life planning and batch managmenet. In APO CDP is activated.

I am trying to prepare APO for CDP and batches. Therefore I created organizational area in SAP ERP and APO.

In SAP ERP I created an organizational area as follows:

Tranx: O1CL

table: Mara

org. area: class type: 023 and 300 for the same org area P

IN APO:

Table: /SAPAPO/MATKEY

organizational area: class type 400 and 300 for the same org area P

Later I will create characteristics and classes (class type 023 and 300) and transfer them per integration models to APO.

My questions are:

1. Is is ok to assign the class types 023 and 300 in ECC to the same org area?

2. Do I really need to assign class type 300 to the same organizational area P which has the calss type 400? or is just 400 enough?

3. Do I need to consider something else?

thanks for helpful hints in advance!!

br,

Wojtek
