Carrier from SO to PO - E1 9.1


Hi all,

First of all English is not my native language so, please excuse typing errors.
In the automatic process of creating a purchase order when the sales order is created, Is there a way to avoid the population of the carrier number (ANCR) using processing options or configuration? Now when the purchase order is created from the sales order, the carrier is the same than the sales order (the one that is associated to the sold to number), and my customer wants in the purchase order the carrier associated to the supplier.
I do not know the way and I would like to avoid modify the code of the application.
We are using E1 9.1 version.

I am not very experiencied in JD Edwards so, please forgive me if is an obvious question.

Thanks for your help!
