Keep parameters in a drill-through report.

Hello and thank you for your help,

I have the following problem with my report:

I created a drill-through report, so that on a click on a Group-cell he shows me the details on this and hides all other details of other Group-headers:

Group_Name1
Group_Name2
........... Detail1
............Detail2
Group_Name3

Now I have a report parameter in the background. This parameter is set to a default value. Now while executing the report in the Birt Viewer I want to change the parameter. This is no problem and the report is reloaded with the given parameter. But if I click on a new Group-cell after that, the parameter is back to the default value.

Is there a possibility to keep the changed parameter without having set it to "is required" (so without having the parameter box poping up each time you click on a new group).

Thank you in advance

Evgeny

Hi Evgeny,

Can you post an example of this issue with the sample database so I can see it. Thanks.

Hi mwilliams,

I have attached the report with my problem and the sample data.

As you will see, when you change the "From" and/or "To" parameters, the report is re-executed with this parameters, but after clicking afterward on one of the hyperlinks the parameters are set back to the default values.
My goal is to keep the changed parameters without having the parameter box appearing each time you click on one of the hyperlinks.

Thank you for your support

Evgeny,

You should be able to go back into your hyperlink editor and send the values through for the from/to parameters.

Let me know.

Hi and thank you for your reply,

the problem with this solution is that each time a hyperlink is clicked the From/To parameter are changing according to the from/to data which is inside of the group. So that the from/to span is getting smaller (just sometimes equal) each time a hyperlink is clicked. This is not a very good solution since the parameters are changed. I would rather like to have the parameters not changed once I have put them in.

I enclosed the updated report to show you my problem.

Thanks for further support

Evgeny,

You need to pass through the actual parameter value, not the current row value. "To" should be passed, params["To"].value and "From" should be passed, params["From"].value. Hope this helps.
