Query about generating report for entire Organization

Hi All,

I have a question about one of my customer regarding vCenter server Chargeback.

We have got an organization in which we have 3 different Org vDC's. Each with its own network, Host and storage type, hence vCPU unit cost, Storage unit cost is different for different Organization vDC's, now we have to create different pricing model for each of the organization vDC's as each Org vDC has its own set of resources costing differently per unit.

But customer is looking for generating single report against entire Organization. So how can this be achieved ?
