BIRT Group Functions Plugin

2012/12/11

Grouping within a BIRT data set
In the context of the Plug In 2 BIRT Contest for Autumn 2012, I created the Group Functions plugin. You can find the plugin, documentation and a sample report on birt-exchange Devshare. The group function aggregations in the plugin make it possible to generate the SUM, COUNT or ROWNUMBER by a group of data within a BIRT data set. With the right combination of these functions and the use of filters you can create many-to-many relations in a joint data set by first applying grouping in your data sets. You can read more on this in the pdf that you can download from the link mentioned earlier.

Screenshots
Here’s a screenshot of how a computed column is created with the GROUPSUM function:

And this is the result in the preview results area of the data set:
grpfResult

You can vote
The contest closed on november 30 and now registered birt-exchange users can vote for the plugin they like most on birt-exchange (the poll is in the sidebar on the right). So if you like this feature, give it a vote. Thanks!
