Power BI Report Builder - Oracle Source!

Hi,

What is the syntax in the Data Sources section of Report Builder for Oracle.

It asks me to enter a Servername.

Here is my tnsnames.ora entry

AAA.world =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = BBB.corp.can.ca)(PORT = 1577))
)
(CONNECT_DATA =
(SID = CCC)
)
)
