CM21 - Change object description

Hello,

I'm trying to change color and text of production orders in capacity planning table (CM21)

I'm able now to change colors dependes on the status.

But I dont find the place how to define description for objects?

E.g. I want to have for production order -  Prod. Order Nr, Material Nr., Material Short Text.

Please help me the required steps to change the settings.

Thanks,

Evgenij
