As part of the configuration of the electronic account statement, external transactions must be assigned to a posting rule. The system uses the posting rules to determine which bank or subledger accounts to post the transactions to.

Posting rules are represented in the system by a non-bank-specific code (for example, 0001 for debit memos).

Why do you require an internal code that is related to the posting rule in order to configure the electronic account statement? Why is each posting rule not directly linked to an external transaction?

Banks have many different transactions, several of which may require just a single posting in your accounts.

• Transaction code 004 denotes a direct debit by debit memo

• Transaction code 005 denotes a collection authorization by debit memo

• Transaction code 020 denotes a transfer order by debit memo

These three external transactions all require the same posting in your accounts. They must therefore all be assigned to the same posting rule (for example, 001 for debit memos). This posting rules tells the system how to post a debit memo.

Using internal codes (posting rules) when configuring the electronic account statement has the advantage that you only need to determine how a transaction (for example, debit memo) is posted once and not three times (as in the example above).
