Hi Matt,
Many thanks for your reply, I'll definitely double check with the people in charge of our EA with Microsoft, that's a possibility I hadn't considered.
It's funny, it sounds like my role up to this point is the exact opposite of yours - I'm responsible for our SQL Server Environment (over 100 instances, over 1000 databases) for all areas except for SAP.
The biggest hurdle I think I have to overcome at this point is coming to grips with the thought that SAP just does things differently. It's just that I see a potential cost savings of 55k, and I feel like even though it's not my money, I'd be a fool to not do everything in my power to try and realize those savings
Thankfully, I have a good relationship with "The SAP guy" here, so I shouldn't have much of a problem obtaining an S-User login......assuming it's a simple process 
Thanks again for your reply!
Steve
