Error when change status period from Stopped to Closed

Hi,

I having problem in AX 2009 while in the general ledger --> periods, i have to change status period from stopped to closed.

i have successfully close at few month, but at with some month i facing the following error :

"Transaction exist in the inventory journals for the current period"

I have checked : all inventory journal, AR, AP and General Ledger, There don't have any pending journal.
