How to replace customized sales order confirmation report in place of standard ?

I have a new customized sales confirmation report. I want to replace the new report with the standard sales information report. I have changed the code in printjournal method of custconfirmjour table.While generating the sales confirmation report it’s printing all the sales order confirmation in the report. i want a particular sales orders confirmation report.Except this printjournal method where i need to change the code so that i’ll get the particular sales confirmation report for a particular sales order.

sales order detail–posting–confirmation-- sales confirmation report

You have created a report and you never told that which sales order to be printed to the report…(use initFromCaller method ).

Rather than going for new report - I would suggest you to add a new design to the same report and use the standard report…
