Drillable Charts in 1.6 using Database delegated

Hi All,

Charts should drill from year->quarter->month. My data source has all these dimensions along with a dimension for filter(Cabins) and measures.

Measures are percentages are database delegated at Universe level for this reason.

In Edit Initial View of the data source,  measures appear OK only when all the dimensions (Year, Quarter, Month and Cabins) are available in Columns. But I cannot have all dimensions always.

For Drill down am using syntax removeDimension and addDimensiontoRows; as a result of which am getting NOT_EXIST for measures which appear as 1,0 in charts.

Is there a way to achieve the drill functionality for database delegated measures using a single query?

Thanks & Regards
