Statistical postings are transactions where you always post to the same offsetting account. For example, when you post interest due, you always post to the offsetting account "interest revenue". To simplify the posting procedure, you can define the number of the account required for the offsetting entry in the system. The system then posts the offsetting entry automatically. Also when you clear open items in an open item account, the system automatically clears the relevant open items in the offsetting account.
