Database Software

LS,

I defined a new module of type data source. This data source is a schema on a physically and logically different server (compared to OWB and datawarehouse instance). The DBA has created a DB-link for me which I can use to retrieve data from that data source.
However, I simply cannot find out how to use this predefined DB-link. The drop down box does not show any existing links NOT created in OWB.
Creating a new link is possible, but now I don't know whether I'll run into problems when trying to deploy this link.

Does anyone know whether it is possible at all to use DB-defined DB-links?

Thnx.
