<p>Hi,</p>
<p> </p>
<p>I have created a pie chart which gets filtered by a cascading parameter group. The data for report items is being taken from a data model instead of creating data sets at the report level. </p>
<p> </p>
<p>I want to have a "All" option in the list box. We can modify the query text based on the parameter selection if we are populating the list using a data set but i want the .</p>
<p> </p>
<p>I request any of you to help me in achieving "All" option if data model or data sets from a data design file is used.</p>
<p> </p>
<p>Thanks in advance!</p>
