hai experts..

no user exits are available for the transaction screen(BP),

i checked 4 the BADIs also for that screen using SE80 t.code,

by entering package name of that transaction code screen..but

no objects are available..

i need a small clarification that if any screen or transaction

doesn't have userexits n badis ,then how to customize a screen

with out using accesskey?

one more thing how to find badis available for a screen to

customize( using other than SE80)?
