Question about 'Redirection' in the Spotfire Data Source

Hi all,

I have a physical layer data source and the type is ORACLE, and one analysis which based on this data source. Now i add one command 'ALTER SESSION SET CURRENT_SCHEMA = AML;' in the open session commands, and then i redirected the schema from 'AML' to 'ORI',but i didn't change the data source connection URL.

After the changes, i checked the columns path, all have changed from 'AML' to 'ORI' and the information link SQL also couldn't be opened. But the information link still could work when i checked the analysis. So who can hlep explain why the information still could work even though couldn't be opened? 

Thanks very much.
