How to know which measure(expression) I selected

How to know which measure(expression) I selected?

For example:

Date SaleAmount Qty

2009 10000 22

When I select on "1000", how to know I select measure "SaleAmount"?

My client told me to clik on "10000" and show the detail data after clicked on it....

On the Layout tab in your detailed data properties, you could set a Conditional Show of getPossibleCount(SaleAmount)=1. If your users have selected a single SaleAmount, or have otherwise narrowed down the possible values to a single SaleAmount, then the detail data would show. Otherwise, it would be hidden.

If the data is calculated by expression "sum(somefield)", when I click on it, GetPossibleCount(somefiled) returns the count value, not 1.

So I think your answer can solve some simple questions. Anyway, Thank you. 🙂
