Passing Paramaters to Standard Quick Create Inport

Hi Everyone,

I have a standard Custom BO from that I am trying to create an Opportunity.I am successfully able to call the Standard QC of Opportunity.

But my actual requirement is to pass my Custom BO's alternative key to the Opportunity Object while creating and also few fields like Account ,Owner needs to be picked up automatically while calling the QC of Opportunity.

I dont have any idea on how  to extend the inport of Opportunity QC to add these parameters.

Kindly provide me an approach to handle this scenario.

Thanks in advance.

Regards,
