To define default account mapping

If you are not interested in the detailed mapping to ledger accounts of some integration transactions, you can optionally map the integration document type to a default account. All the transactions for the integration document type for which LN cannot determine an account based on the mapping scheme details, are posted to the default account.

You can map the debit side or the credit side of an integration transaction, or both, to a default account. For example, you can map the debit side to a default account and define a detailed mapping for the credit side.
