AFVGD-MATKL as required field

[unurd]

Hi,

I wish to make field AFVGD-MATKL required, when AFVGD-STEUS is e.g. PS04, external service.
Didn't find it in customization.
Is it possible only in save user exit?

Thanks, Amos.

I've searched all over, and bought a couple plugins rather not badmouth them but I have yet to find a plugin that works which will make a text input field required. Radio buttons, select list, yes I am able to make them required with Custom Fields For All. But not text input. Help? There's got to be a working plugin out there for this, right?
