Hi,
User is trying to post a payment journal in AX 4.0, when she validates the journal it shows correct, but when she tries to post it she's getting this error:

Taking a look to the journal, the second line doesn't have any linked transaction, there is no transaction to select since it has not billed yet, they PP (put it on the account) the payment. Per user this is something they normally do and comparing with another similar journal apparently they do.

Journal seems to be correct, it's balance. Another thing we noticed is that account type and legacy order account are different, per user this is correct too, It’s first the master account and then the actual account.
It called my attention that I don't see the master account listed in the account type dropdown list, they typed in the number.

Please let me know your thoughts.
Regards.
