While entering vouchers, you can mark them as post dated, as a result these vouchers are not updated in the ledgers till the date specified in the voucher. This is useful for entering transactions that take place on a regular basis. For example, if you issue post dated Cheques towards payment of installments, you can set up the payments in advance, and Tally.ERP 9 will only update them in the ledgers on the due date.
Mark vouchers Post Dated by using CTRL + T or click on the button Post dated from the Button Bar. This button toggles between Current and Post Dated.
