How to extend SAP APO SPP product master data with additional fields?

Hi, I'm an ABAP resource. just moved to APO and my client is implementing APO SPP solution. for that i have a requirement to update SPP Product master data(below are the details). please provide any details from technical perspective.

APO SPP Product Master should have the following user required fields (provided that values are populated from SAP ECC Material Master):

- Division

- External material GRP

- User plant / Generation Plant

- 3 Product Classifications (M6, M9, M10)

- Material moving average price

- Last PO price

- Final Price (ZCAP- Last PO Price and ZSTK -Moving Average Price)

- MRP controller

- Material type

The changes to these fields also have to be updated automatically in SPP.

please provide details if anybody knows how to achieve this functionality.

Thanks in advance for your help.
