ATP based on material and capacity availability

Hi Experts,

Is there a way to implement ATP with finite capacity availability and material availability in a Make to stock (MTS) environment in R/3? In other words, when a sales order is created for a material, the confirmation date that is recd. should be based on Capacity and Material availability. What planning strategy would you use?

I understand that this can be implemented in assembled to order environment (planning strategy 82 or 83), but my question is more related to MTS environment.

Regards,

Praveen
