How to determine Delivering plant logic if 1 Sales org and 3 plants

Hi All,

We need your help to identify a logic for the below scenario,

we have one Sales org and 3 different plants

Slow moving material will be delivered from one plant and fast moving material will be delivered from another plant.

One material "XXXX" can be a slow moving material for one plant and fast moving for other 2 plants.

Could you please tell us how do we identify a solution how to determine delivering plant when a sales order is created for this scenario.

thanks

Prabhu
