Within Teamwork.com, you can generate an activity report which covers all active projects on your site.
Note: Standard users and above in the owner company can generate an activity report. External company users need to be a site administrator to be able to generate it.
Click the Projects option in the main navigation menu on the left of your site and select the List tab.

To the top right of the List area, click the options button (three dots) and select Generate Activity Report from the dropdown menu.

When creating the report, you can choose from different options such as date range, who will be included in the report, and which items are included.
Note: The projects activity report is limited to 1000 entries.

You can download the activity report as PDF or view as a HTML document.
