I've Sales Report (Target report) with measures sales amount, average order, GP$ etc
I did sorting for those measures, If we select particular measure it has to show as per the sorting order
it is working fine, In default selections I took "sales amount" when I run the report is has to show the sales amount

my question is

when I run the main report, after clicking on the sales report(Target)

it is showing the parameter value sales, data is blank. again I 've to select measures for the drop down list (it works)
it has to show by default sales amount ( when I run target report  is is showing sales amount)
the problem is when I am running this in main report

please share your ideas
