userexit for smartform logic

hello experts,

i designed a smartform now i have to assign a printprogram for it

in our company there is one customised transaction when it is executed v r getting one form output now i have to add this new smartform at that point sothat i can get output along withthe existing one

so for this i identified the position where the previous smartform function modele called when i am trying to change that funcation moduel it is asking for the access key

previous developer written the data retreival logic in an include with userexist in the form of routines n he called those routines in that above fm so how to edit it so that i can add my form logic there

Thanks in advanse
