Functions doesn't work with the ODBC connection

Hello everyone,
I have lately install an ODBC connection on a new server that we have set up.
 
I connect to the database through Qlikview (a datavisualisation tool), it works well except when I want to use a teradata function.
 
For example:

I get a syntax error. I've tried with several functions and always get a syntax error... Of course, I have checked the SQL query was ok and it is !
 
Do you have any ideas ?
