This function batch posts any transactions that have not yet been posted to the Nominal Ledger. In particular, this function is used to handle the automatic posting of sales transactions that have been printed as invoices but not yet posted. You cannot print up-to-date Nominal Ledger reports, analyse transactions, or make counter postings such as invoice receipts, until you have posted all transactions to the Nominal Ledger - although Enterprise 6 will always remind you of this if you try to print such a report.
