I add a new message number '020' for application area 'F0' in OBMSG,
and set the message type 'warning' ,
then add this message number for F0 application area in OBA5,
BUT , it doesn't work , when I execute transaction code F110 ,
and when the next posting date early than post date ,
it still appear the error message (it show : the next posting date need to later than the post date),
and I'm confused why the setting above doesn't work?
if this message number may not allow us to modify ,
if there any method to change the message type from 'error' to 'warning' ?
Thanks a lot for your help.
