Bill the customer based on Profit center

Hi,

We have a requirement on billing where we want to bill the customer based on Profit center. Profit center is assigned to a material in the material master and defaults on sales order. So whenever we deliver the materials, we want to bill customer based on profit center. For instance, let us say there is a sales order with 5 materials at line level with 5 different profit centers. And ship all these materials against only one delivery doc. When we bill the customer using VF01 or other billing process, we should get 5 billing docs based on 5 profit centers. Is there any user exit or config to accomplish this functionality? We are using 4.7 version.

Any ideas would be really appreciated.

thnx
