What do we mean by ' ' value in authorizations, i have a auth. field , where i have maintained all the possible values for that field , but the end user SU53 shows ' ' missing , can someone please explain the concept of ' ' value.
As per my understanding, by maintaining all the values i am restricting the end user to enter one of these values only, but in case the end user does not enter any value there , then error comes. Am i on the right track ?
