BADI and Screen Enhancements

Sear Experts,

im trying to implement a BADi which contains a few screen enhancements:

I've insert the program name as well as the subscreen I'd like be implemented:

But when Im trying to activate all it i get following error:

What does it mean? How can I activate my implementation?

Thanks in advance.

BR, Denis

UPDATE: I solved the problem with adjustment, but I still cant's see my subscreens in the transaktions. What did I miss? And how I can find the PBO/PAI - Modules for these Subscreens?
