PO print: cost of the monthly container rental and the cost of the consumption of the product

Hi guys,

the requirement of my customer is to have on the PO print:

• the cost of the monthly container rental
• the cost of the consumption of the product

I am going through hard times because maybe for the first request could I use a freight condition correct?..But for the second request I should not have any idea...Any suggest?
