Periodic Unit Price not update/release to Standard Price

Dear Gurus,

We have a problem, when closing period is done the PUP (closing period) not update/relase to Standard price (in future period).  We have checked all the steps during the closing period, and all seems to be right.

The closing period is not more than 2 period, we closing April 2014.

I have checked note 666681.

Maybe Gurus can tell me something that i missed.

Please help

Regards,

Beto
