I recently ran into this when trying to make a DIEN (service material type) configurable. It let me check the box and everything was fine until I tried to add a configuration profile. (CU41). No matter what I did, it wouldn’t allow me to add the class. It finally hit me, the classification screen wasn’t active in class type 300 for the DIEN material. If you run into something similar, here’s how to fix it.
SPRO -> Logistic – General -> Basic Setting -> Material Types -> Define Attributes of Material Types
Select the material type and select the detail screen.
on the right side of the screen there is a list of screen. If the screen you need (classification for me) isn’t highlighted, simply highlight it and press save.
