How to set MULTIPLE repository variables using presentation variables

Question

Hi,
I need to pass multiple values from presentation variable to repository.
A brief about report design :
I have two repository variables - from_dt and to_dt which are defaulted to some values from a database table and are editable by the user.
I display these default date values on the dashboard. Plus there are two dashboard date prompts allowing user to enter a date range different from what is displayed by the from_dt and to_dt. The dates entered by user are assigned to presentation variables pv_from_dt and pv_to_dt.
If user specifies a different date range then these date values are to be passed to a stored procedure which is called from the Connection Pool --> Connection Script Tab --> Execute before query. This procedure will do some calculations and populate a global temporary table before running the report.
Problem :
Now in the presentation server, in the Advanced tab, in the Prefix section, when i try to write something like this:
SET VARIABLE from_dt = '@{pv_from_dt}';
SET VARIABLE to_dt = '@{pv_to_dt}';
I get the foll error :-
Error Codes: YQCO4T56:OPR4ONWY:U9IM8TAC:OI2DL65P
Odbc driver returned an error (SQLExecDirectW).
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 27002] Near <SET>: Syntax error [nQSError: 26012] . (HY000)
I tried all possible permutations and combinations
SET VARIABLE from_dt = '@{pv_from_dt}',SET VARIABLE to_dt = '@{pv_to_dt}'; --- gave same error
SET VARIABLE from_dt = '@{pv_from_dt}' SET VARIABLE to_dt = '@{pv_to_dt}'; -- gave same error
How do we assign values to multiple reporsitory variables... ???
Thanks

Hi,
I wrongly referred to the variables as "repository" variables. Both variables are Session variables. For testing i added a column field in the report with source as the session variable - VALUEOF(NQ_SESSION.from_dt). In the Prefix section i assigned a literal value - SET VARIABLE from_dt='01-JAN-2012';
When report is run, the literal value gets displayed.
The idea to update a session variable, from dashboard using presentation variable, i got from the following URL.
Go to http://oraclebizint.wordpress.com/category/obi-ee-plus/page/11/
and see the section "Oracle BI EE 10.1.3.3/2 – Updating Session Variables from Dashboards using Presentation Variables"
Thanks
