Handling parameters when using BI Server as a Data Source

Question

Hi,
Following an upgrade of our BI Publisher 10g content to 11g I've come across a syntax issue with 11g when it comes to the handling of parameters in BI Server Data Sets.
Under 10g, the documentation stated the following:
+"If your data source is the Oracle BI Server, use the following macro to handle the null:+
+{$ if ${sYear}='*'$}+
+{$elsif ${sYear}='2000' $}+
+where Year = :sYear+
+{$else $}+
+where Year = :sYear+
+{$endif$} "+
http://docs.oracle.com/cd/E10415_01/doc/bi.1013/e12187/T518230T518233.htm
Under 11g it does not seem to allow the use of macros defined in Data Sets and raises the following error when saving the query:
+"java.io.IOException: prepare query failed[nQSError: 43113] Message returned from OBIS. [nQSError: 27002] Near <$>: Syntax error [nQSError: 26012] ."+
If macros are no longer supported, what is the best approach to handle null value parameters (caused by all choices / nothing being selected)
as they need to be defined in the Data Set WHERE CLAUSE?
I've tried a rather clunky CASE WHEN statement which handles string parameters fine, but dates are another thing as null values are returned as 'null' text which causes TYPE mismatch errors.
Hopefully there is an elegant way to handle this in 11g (the 10g macros were very straight forward when dealing with BI Server)
Many Thanks

If what you are saying is true then I would highly recommend open a ticket with Oracle Support.
They should provide and alternative for handling NULLS in 11g.
