Task option: "Step not in workflow log"

[Rick Sample]

PP01 change in prod env. ?
 
I was told that HR folks would have PP01 in the prod env so 
I setup a 'Responsibility' for a role in a task. 
Now it has hit production and no one seems to have the 
correct security auth. 
 
When using Responsibilities, what is the typical t-code 
to use for production changes? And what security auth 
should they get?
 
Thanks!
