I need to post custom warning massege in ME21N,ME22N,ME23N transactions whenever user clicks on check button OR after entering GL account and press enter.
I need to validate GL Account field & give "WARNING' massge (W) if GL Account does not match with the with Z table entries.
i have also used below method but it is not working .
MESSAGE w398(00) WITH 'a' 'b' 'c' 'd' INTO gl_dummy.
mmpur_message_enaco ' ' '00' '398' 'a' 'b 'c' 'd'.
also i can not use any function module because many BDC's are also being used in many programs.
Please provide your valuable suggestion.
Thanks & Regards,
