You create one interim account for each of your bank accounts (see Creating and Editing G/L Account Master Records).

You then specify which bank account it is related to. To do so, in Customizing for Financial Accounting, choose Bank Accounting ® Business Transactions ® Bill of Exchange Transactions ® Bill of Exchange Receivable ® Present Bill of Exchange Receivable at Bank ® Maintain House Bank Details, and enter the interim account number in the Collection acct field (Collection account).

You then have to specify which liability account it is assigned to (see Bill of Exchange Liability Account).

When you come to present a bill to a bank, you specify which interim account it is to be posted to. The system then debits the bill to this account pending clearing. Later, when you post the bill as cleared, the system transfers it from this account to the bank account. On the other hand, if the bill bounces, the system transfers it to the account for the bounced bills portfolio.

You create a single interim account for all of your vendors. You then assign this account to each bill of exchange portfolio (other than those that are used for bounced bills). To do so, in Customizing for Financial Accounting, choose Bank Accounting ® Business Transactions ® Bill of Exchange Transactions ® Bill of Exchange Receivable ® Post Bill of Exchange Receivable ® Define Bill of Exchange Portfolios, and enter the interim account number in the Int. acct field (Interim account).

You then have to specify which liability account it is assigned to (see Bill of Exchange Liability Account).

When you present a bill to a vendor, you specify which portfolio the bill is from. The system creates two accounting documents, the first of which debits the bill to the interim account that you have assigned to this portfolio. The second accounting document transfers it from this account to the vendor's account, to reduce the amount that you owe the vendor.
