Future Period

 Good day. I wanted to ask for some assistance in figuring out why we could not create a receipt under a purchase order in the Purchasing module. We are receiving an error message, "APP-PO-14376 Please enter a GL Date within an open purchasing period..."

Due to some financial reporting issues, we decided to close the period AUG-10 a day earlier that normal (closed on 8/31/10 instead of 9/1/10). After closing Payables and Purchasing for AUG-10, we tried to make a purchase order receipt and received the error message. I noticed that the date of the receipt was showing as 8/31/10, so I was wondering if Purchasing would not allow the receipt as AUG-10 was closed. So, we attempted to change the receipt date to 9/1/10 only to receive the error message that the period was not a future-enterable period.
