Bank account does not exist - AX2012

Hi,

I have a problem with posting of transaction in account payable payment journal. I have voucher:

1 line: - account type = vendor, offset account type = 0                Debit 500

2 line: - account type = ledger, offset account type = 0                 Debit 200

3 line: - account type = bank, offset account type 0                      Credit 700

all lines are one voucher number. the second line is fee on payment and voucher must be posted like this. During posting of a journal, error "Bank account does not exist" appears. It is because of the second line. But i dont know why. What is wrong? In AX2009 voucher like this can be posted.

thanx
