I had to deal with the same crap.

3rd part application was the requirement, and SQL/Server was the default, but if we got a certain ODBC driver all would be supported. It didn't matter. The program still blew up.

But that was a LONG time ago.

This company's drivers was one of the better ones to deal with. But EVERYTHING still needed to be tested.

If you have a serious grind through test suite, use it. If not, get it from SAP, don't bet your job on it working, make them certify it.

You don't want to be in the middle of "month-end" processing only to find out it doesn't work in your special case.
