Wise! 
We are audited by the State annually, and in the fourteen years I have been with my current employer, managing our SAP system, only once has a State auditor asked for direct access to the system. Every other year they just ask for reports or extracts from it and are happy to let us provide them. Actually, most years the auditors don't even talk to IT; Finance deals with them and it is Finance that asks us for the extracts and reports. We have had a couple years, though, where the auditors wanted to look at things like the history of all transports to production in the course of a given year, and then they picked two (seemingly at random) and asked for the documented approval chain for them.
A few years ago our internal auditor asked for access, and so we do have an auditor role for that. However, as that person is an employee, they would have an account anyway for ESS purposes, so it was just a matter of adding the additional role.
