Contract price is not copied to PO

Hy friends,

I'm having some trouble copying the price from contract to PO , when creating a PO in refrence to a quantity contract.
I have checked everything but nothing works , if anyone have faced the same problem before please advise,

NB: I have the same customizing in the Qual envirement and PO does inherite price from contract , but it's not the case in the Prod.

thanks in advance,
