Eliminating duplicates in a dataset

ststrou

<div>I have a BIRT report that reads from a UML model data source.  The report has a dataset containing all of the Actors appearing on a use case diagram.  Then in a List, I print the name and description of each of those Actors.  In some cases the same Actor appears twice on the diagram, in which case BIRT dutifully prints the Actor name/description twice.  I would like to make it smarter, so that it only prints each Actor name/description once.  Since this is a very common situation, I would think BIRT would have some way to easily handle this presumably common situation but if so I can't find it. I tried using a table instead of a list and enabling the "Suppress duplicates" checkbox on the column but that had no effect whatsoever. Anybody know how to do this?</div><div> </div><div>PS: I am using BIRT 2.6.2 (included in Rational Software Architect 8.5).</div>

<p>You're wanting to have the duplicates suppressed in only this list, correct?  You could group the list on the actor name and they should only appear once.</p>
