Wrong G/L account in MIRO

Hi guys,

my problem is this: I have a Purchase Order with only flag 'Invoice receipt' because I don't want good receipt and in accounting label I have a certain G/L account.

Now I run the MIRO but I click the button 'simulate' the system takes correctly the G/l account for the vendor BUT doesn't take the G/L account in the purchase Order but the G/L account 'Accrued Receivers Auto' like if I have done a Good receipt...Why the system takes this acconunt and not the mine in the PO?

thanks in advance bye
