How to enable incremental updates

This procedure assumes that you have already created the data object design (.datadesign).

1	In the layout editor, right-click in an empty area of the data object design.

2	Choose Enable Incremental Update.

After you publish this data object to iServer, incremental updates occur each time the data object is generated. Depending on the job properties that you specify, iServer replaces the existing .data file with the updated version or maintains multiple versions of the .data file. Dashboards and BIRT Studio reports configured to use the latest .data file display the new data when users refresh the dashboard or report.

If you share the data object in a file system with other report developers using Actuate BIRT Designer, you replace the .data file manually.
