Authorization for tcodes created for table maintenance

Question

Would appreciate if you could answer my questions:

1) If I created a Z transaction code for maintaining a Z table that has authorization group not equals to &NC& and data browser/table view maint is set to Display/Maintenance Allowed with restriction, Does that mean the Z tcode will also be restricted to few users?

2) Is there a way to know who are authorized to run a certain Z Tcode created for maintaining a table?

Answer 1

To accomplish this in SUIM go like this: User -> Users by Complex Selection Criteria -> By Transaction Authorizations

There enter tcode and press F8.

Answer 2

Ad. 1.) No, it won't.
Ad. 2.) Yes, there is.
