I know it is not possible to change the mandatory field "Person responsible" (VERAK) to optional through customizing. It should be changed by user exit (it this is possible, of course). I have been looking this point (exit COOMKS1 or COOMKS02....). But I do not know if it is possible, yet. I`ve read that the field is harcoded in the ABAP code so it is impossible to change it.
Has anyone had a recent experience on changing this mandatory standard field (VERAK) to "optional" through a user-exit? Which one and how?
Thanks to all of you,
