Cost Break Up of Internal Orders-Overhead

Hi mates,

I have created an internal order with an object class: u2018Over Headsu2019, for which costs were pooled and finally internal orderu2019s balances, are to be settled against the FG material.

I want to see the cost components breakup for the costs incurred in the internal order.

Can anybody help as how and where to link the cost component structure to the internal order, so that I could see the cost break up and also request to give the areas of integration between Project System and Controlling

Thanks in advance

KS
