Report Viewer

Description

The Report Viewer component provides a way to run and view Reports in Vision windows. Parameters added during Report creation are provided as Properties in the Viewer and can override any default values set in the Report Resource. Right clicking on the Report Viewer brings up a menu that allows you to easily print the report or save it in various formats. The Reporting Module comes with some additional reporting components that can be used with Vision components. To learn more, refer to the Vision Reporting Components section in the Reporting Module. To find documentation on the deprecated Report Viewer prior to Ignition 7.8, see the Legacy Report Viewer documentation.
