I have the same problem, when we try to do a OLE(ADO) connection there is no problem, but with SAPBusinessOne connection the DB do not appear in the combo connection and after you click ok on this window appear the José error.
I have win 2008 server R2 with all updates, SQL 2012 sp2 and SBO 9.0 PL04 with Crystal Reports 2013
Best Regards
Mauricio
