First of all, let me describe, what I did:
I created a number of tables and some views within a oracle 11g db.
I created a connection, secured it and build a multisource DF on top of it.
Now I started building the universe on top of it. It all worked very well, except 3 columns of a single table. This table is not connected with any other tables und reflects a view. I have other tables which are views and those work perfectly good.
If I press the "Show Values ..." Button, it throws a:
Failed to execute: SELECT DISTINCT
Table__26."COL2"
FROM
"DEMO-CONNECTION"."SCHEMA"."TEST_VIEW" Table__26
Cause of Error
[Data Federator Driver] [Server] The column name 'COL2' could not be found in the table/alias: 'Table__26'
The column exists. Recieving row from the TEST_VIEW with Developer works to, recieving rows from other views inside IDT works as well.
I tried recreating the TEST_VIEW, I even put a dummyvalue inside the columns with errors but it did not work. The SQL does not get fired on the DB (verified this by looking at V$SQL).
Any suggestions?
