links tab

Hi All,

I have a small doubt.

I have main report having empno column. I created a parameter empno in command level.

And I have a sub report which also having empno.For this also I have empno parameter in command level

I want to pass empnos from main report to sub report .So I linked both report empno parameters using links tab.

Now is it required to link empno fields also of both main and sub report again.

Please suggest
