<p>Hi Everyone! I'm new to birt and I want to implement the cascading features in birt report. </p>
<p>How can I achieve that?</p>
<p>I followed some online tutorial but it didn't work. </p>
<p>Basically, I created a cascading parameter group which contains two parameters, user_id and transaction_id. The hierarchy is each user_id have multiple transaction_id. The report will let you choose a user_id first and then choose the transaction .</p>
<p>My query is something like this :</p>
<div>select distinct session_id, user_id,user_name,transaction_id,request_id,execution_step</div>
<div>from table where user_id =? :</div>
<div>I also add the parameters in the data set. However, my report didn't work.</div>
<div>Can anyone help? I was trying to find an example here but a lot of the links didn't exist any more. Thank you so much! </div>
<p> </p>
