Sales Order Sold To Contact

I am writing a baq for a sales order dashboard and want to add the Customer Sold To Contact. I am linking the OrderHed.PrcConNum to CustCnt table. But in several instances I get multiple rows returned for the same order as there may be two customer contacts whose ConNum are the same relating to previous orders. I know one ConNum relates to a ShipTo Contact and ShipToNum is used as a 2nd key. Is there a 2nd CustCnt field to determine the SoldTo Contact?
