MDO Datasource Issue in SAP MII 12.2 ramp-up

65 Views

Hello MIIres,

I'm trying to configure the MDO Datasource in MII 12.2 (ramp-up) but unfortunately I having some issues. First of all, I successfully created a Custom JDBC Data Source in NWA to map a SQL Server 2005 database. But after this, when I try to put it in the MDO DataSource in the System Properties under the System Management menu, I receive an error as follows below.

Does anybody knows what's going on?

Thank you very much guys!
