WTpart & EPM-Layout customazing

Hello everyone,

I want to customaiz our WTpart & EPm-Doc.- layout so that we can see the Promotion request Approver on the side.

But i can´t find the right (WT_CN_Approver) in the attributelist in the type & attribute administration.

Is this even possible?

Thanke ahead for your time.

Sincerly

Philipp
