Is it possible to pass variable to a sub dataset..?

[jo_m]

Hi all,

I am using jasper studio 5.5 and I have a variable in my main report. So I want to know that, Is it possible to pass main report variable to a sub dataset…?

If it possible, please share with me - how we can pass the variable to a sub dataset…?

Thanks!

You can pass values from main report variables to a sub dataset through parameters. It requires two steps to do this:

1) create a parameter ($P{x}) in your sub dataset with the same data type as the variable ($V{y}) date type you want to pass

2) in the report component (table, list, charts, etc) using the sub dataset, add the parameter in the sub dataset to pass the values $V{y} through $P{x}

Parameter: x

Expression: $V{y}

This will pass variable y to sub dataset through its parameter x at the run time when report component is called.
