Frieght Price/scaling in Stock transfer order

Dear All,

I have a business scenario, where I am doing the Stock Transfer between the plants and there is a frieght vendor who will do the physical Stock transfer to other plant. For this Frieght Vendor, Client wants to make separte annual contract which he wants to settle through Service Entry sheet.

Kindly suggest me the right way for doing this in SAP. I have added this Vendor to the frieght condition and it is working fine. But by this way, system will pick the price maintained in Frieght condition type. System is not taking the price or scaling maintained in contract agreement (MK).

How can we pick the price & scaling maintained in contract into the STO order.

Thanks in advance
