User exit G103 not declared in form pool ZGGBS000

Hi all,

I get a error GB308 'User exit G103 not declared in form pool ZGGBS000' when exetuting 'ML81N'

but the User exit G103 existed in ZGGBS000 and was added in form get_exit_titles.

in ZGGBS000 program:

form get_exit_titles:

form:g103:

and in ggb1:

Is there a way to get rid of those errors.

Or do I need to do something manually.

Thank you

Best Regards
