Budget Check in Purchase Order with Prepayment

Dear All,

I have a case in Purchase Order. here the explanation:

I create a PO and create the prepayment, posting prepayment invoice, and make a payment of prepayment invoice at January 22th. The Invoice come at March 1st (where the January already changed to on hold status in the ledger calendar). Then when I confirm the PO there is a error shown "a budget check cannot be performed. The fiscal period with the accounting date is not in an open period fiscal calendar period"

I try to check the delivery date, it still shows January 22th then I try to change it to March 1st and I confirm the PO the error still appear. 

I try to check the accounting distribution and I found the field " Accounting date" but it grayed out. 

is it possible to change the accounting date in the PO? if possible, where the menu/feature to change it?

or

what should I do to solve this problem or any suggestion in workaround?

Thanks in advance
