Hi Deepthi,
Just go to NACE, select V1 application->click on Output Types, then find out your output type e.g. AN00 for quotation, select Processing routines, here you found your Print output where Program is RVADOR01 and form is RVORDER01, copy this form using se71, then ZRVORDER01 form created, here create a window like LOGO, on page assign the window on particular position where you want to show logo and include logo in this window by just click on Text where on top you find Insert->click Graphics, Add your logo.
Many Thanks / Himanshu Gupta
