If you have transactions that occur on a regular repeating basis then you can configure Tally to automatically create these on the appropriate date.
To begin, click Bank > Repeat Transactions > Add Repeating Transaction. On the next page use the options to configure the repeat bank transaction, when your ready click the Add Repeating Transaction button.
Please note that the transactions will not be generated retrospectively meaning it is only transactions from this day on that will be created. Similarly, transactions in the future will not be created immediately – instead they will be generated on the interval set.
