Multiple-drill through in crosstab report

[BMbabu]

Hi,
I am facing the following problem in cognos:

I have a crosstab report with one row R and two different columns A and B.
I want to create a separate drill-through for elements of column A and column B. But cognos is not allowing me to do this.Whenever in the drill-through definition i am specifying different targets for these columns,its changing it to a common target report(the one that was selected latest as the target report in some drill-through definition).

How can i create separate drill-through for both the columns each with its own different target report?

Thanks,

use a layout expression, with a CASE statement, that will provide a parameterized URL to do the drill-through.
