Hi Suneel,
2 things. If you want to use Param.1 you can do like this
1) In MDO Select Query, we have to mention Filter Exprn as [dept]=[Param.1].
Here Param.1 is the MDO Object Parameter and [dept] is the attribute of MDO.
In Parameters(Under Template Categories of MDO Query) you have to give the value of Param.1 and select type as String from the drop down.
Now in IRPT you have to use setFilterExpn method in either of the ways rutika mentioned.
2) you no need to give Filter exprn in MDO Select query as [dept]=[Param.1] . If you dont give filter exprn here it will give actual data of MDO and anyway you are changing it through IRPT page.
I am attaching Video for your reference pls go through it.
