Production Order -FMS

Dear Experts,

In Production order Transaction, Sales order reference need to populated. Could you please help me.

SO FIELD NAME :U_IntRef

PRODUCTION ORDER : U_INREF

Actually FMS written as,

SELECT T1.U_IntRef from OWOR T0 inner join ORDR T1 on T0.OriginNum = T1.DocNum

Above FMS displayed all the references from sale order.

Actually my requirement, Sales order against Production order executes through procurement conformation wizard. Respective reference need to populated in PROD Order.
