Advanced bank reconciliation: transferring the bank statement number into Document number (LedgerJournalTrans.DocumentNum) of the automatically generated and posted journal line (e.g. if you process reconciliation matching rule "Settle customer invoice", generating a customer payment journal) would improve visability on customer/vendor/ledger transaction. Actually, only the voucher number is visible and the users cannot directly see, e.g. which bank statement was used to post a customer payment transaction!
