Check authorization role when a new transaction is called

Hello experts,

I have created a new transaction with parameters. I have also created a new Authorization-Role with several users. Now I want to connect the authorization role to the trasaction, so only the users in the Authorization-Role can execute the trasaction.

I tried it including the object S_TCODE in the Auth-Role and giving the name of my trasaction, but it does not work.

How can I do that? Or do I need to create another object?

Thanks a lot,

Robert.
