Billing date in case of Periodic Billing Plan

Hi,

Refer to the above subject,

I face billing posting error due to the billing date copied from periodic billing plan.

This billing type is order related billing (Business process is that stock is leased and post billing for rental fee.) and my requirement is to post billing as billing plan amount except billing date and billing date shall be document date. In addition, this requirement was already applied in other sales organization (in one client) as below :

(1st billing date in billing plan : 30/12/2013, Billing date in all billing documents : 27/02/2014)

Can you advise which setting shall be checked?

I checked copy control from sales order to billing (Header : copy requirement - 001 / Item : copy requirement - 023)

Thanks,
