How to change the pricing during creating followup of same Transaction

Hi Frds,

My requirement is the check the Opportunity date and once it get expire create the copy of same opportunity so that again it get renewable.

Ques: suppose if contract get expire after 2 year and during this time the pricing get change. So i want to update the pricing during creating followup document in report.

I am creating followup document using FM CRM_COPY_PROCESS_PREPARE and then using  CRM_ORDER_MAINTAIN.

so my problem is i unable to update the pricing. Is it possible to update the pricing at the time of creation.

Please advice. Sample code will be appreciable.

Thanks,

Rajan
