Pricing in contract/billing plan

Hai ,

I have a contract with a billing plan. On header level I use a pricing condition. Example: at header level I have a net value of 400 euro. In the periodic billing plan I have 13 periods, each period gets 400 euro.

I want that the 400 euro will be divided over the periods. In this case, 13 periods so each period has to get 400/13= 33,77.

Can you help me to accomplish this?
