Generate Order messages using Different Forecast Types

Hi,

I'm doing planning scheduling implementation for one client. I want to generate order messages using different forecast types. In standard functionality system is generating single order message line and adding up forecast quantity of that item. Coz those items are common in retail and whole sale business, Hence i want to generate separate demand in order messages.

Here is the scenario:

Forecast Type- DR- retail, DW- Wholesale

Forecast Qty- DR-100, DW-100

R3482- Processing options- Forecasting- DRDW

Order messages- WO-200

I want to see 2 order message lines of 100 each.

Pls advice
