When using the text-to-account mapping functionality in Bank Reconciliations you can only specify the account type and account number. There are often scenarios where the standard set up on the general ledger account doesn't apply.

For instance, if an account is set up with one type of VAT posting group but there are a number of transactions going through against that account that require different VAT posting groups it isn't possible to use the text-to-account mapping. Instead you need to send the lines to the general journal and handle manually.
