}

The accounts and subaccounts are controlled by the GL access and the user im logging as does have access, also I can enter the account and subaccount through the UI view with no issue as well.

The only time it does work is if the Supplier has no Expense Account and Expense Sub set or the Account and Subaccount are the same as the suppliers Expense Account and Expense Sub.

Any help would be appreciated
