Merge rows of almost duplicate data in BIRT?

see the table here: http://www-01.ibm.com/support/docview.wss?uid=swg21376096

what i'm trying to do in birt designer is merg开发者_如何学运维e those two rows, and combine the Product column cells, since everything else is the same. end result would be a product cell of "IBM Tivoli Asset Management for IT, IBM Maximo Asset Management Essentials"

Would this be grouping? aggregation? would this be done in the SQL query?

This article might help, it goes through a few techniques of aggregating strings depending on what software/server you are using.

You might need to make a function.
