Hi, Urgently please now when I create a bill for expense not for item, How can I appear all type of accounts not only the expense type account I want to appear also Bank accounts in this bill????

Bank accounts cannot be selected in the Bill. Why do you need to debit the bank account in a bill?

For approve purchases of fixed assets through Bill so I need to put Bank account which I pay for this asset

The bank account must be selected in the Bill Payment Transaction.
