Rebates sales order

In 4.7 sap was working, but now in 6.0 doesn't work anymore.

I'm creating a Rebate sales order, using  -> VB02 -> Rebate Payments -> Final Settlement -> Automatic , and Rebate Payments -. Credit memo request -> Change.

When I look at my sales order all the values is zero. Can you help me, why this is coming as zero ?

I saw the configuration and the Rebate is active.

Thank's
