This feature of IntelliGantt and the IntelliGantt Add In for Microsoft Project allows create and update reports in SharePoint using either Bamboo Solution's Project Portfolio Dashboard or the basic Project List.
Step 1: Using your web browser, copy the URL of the SharePoint Site that contains the Dashboard you wish to use. Click 'Go'.
Step 2: IntelliGantt will communicate with the SharePoint server and list the available Dashboards. Select the Dashboard you wish to use.
Step 3: Click 'OK'. If this is the first time this project has been reported to this Dashboard, a new entry will be created. Otherwise, the previous entry will be located and updated with the most recent project summary information.
