Change field status in screen variant via SHD0
We use SRM 5.0 with the classic scenario.
The problem i'm facing is, that I dont succeed in creating a screenvariant for the transaction bbpcf02 screen 4000 for the field Product category.
When creating a confirmation for a limiet item the field Product category is changable by default. I like to change the status of that field to only display, so I tried to make a screenvariant via the transaction SHD0, but I can't seem to find the field Product catagory. I begin to think that it isn't possible via SHD0.
Is there somebody who can advise me in this mather?
Remark: we choose screenvariants above template adjustments or Badi implementations for a solution
