How it Works

Details for each change include: 

Changed On

The date and time of the change in the your local time

Changed By

The user that made the change. System denotes changes made by the system.


The type of change can be AddUpdate or Delete


Direct - Updated by the user in Clarizen (web or mobile), or via API/workflow

Indirect - Updated as a result of a Direct action. For example, changing a work item's due date can cause the expected progress field to be recalculated.

Component - Changes performed by the system that are part of another operation. For example, adding a new task will also cause the addition of a resource link for the default Owner.

System - Updated/calculated by the system. Scheduled changes such as calculation of "Expected Progress" fall into this category. 

Item Type

The type of item, including work items, user etc.

Note: Shortcut additions and Custom Objects are currently not tracked in Change History.


The name of the item

Related Item

If the change involves another item (such as adding a resource or a dependency to a task), you’ll see the related item displayed here.

Field Name

The display name in Clarizen

Previous/New Value

The value of the field/item before and after the update


Filtering and Sorting

Click on a column header to filter and sort the items.


Time Zone Options

The time zone option makes it easier for users across multiple timezones to compare changes.

This is of particular use when Clarizen Administrators/Power Users located in a different timezone want to assist other users and review changes in a specific timeframe.

The default is "My Current Local Time" as per your computer's current clock setting. 

Live Mode

Click Live Mode to have the screen automatically refresh the Change History every 10 seconds. This is particularly useful when working with multiple monitors and testing workflows or API changes.

Live Mode deactivates after 2 minutes or whenever you manually reload the page.


Item Details

Click the arrow to open the item details in a new tab.


Download Excel

Click Download Excel to export the events to an Excel file.

The downloaded file includes the time zone option, column order, column filters in the view and financial permissions (yes/no) of the User performing the download.

Note: The maximum amount of rows supported is 100,000.

Previous Data

Change History starts recording changes from when this feature becomes available. 


Users with Financial Permissions can see updated financial data for a Project.

Tracking History

The last 1000 changes/ 30 day history is per work item, dependency and resource assignment. 
You can see them aggregated at the Project level. 

A clean-up process runs every night at 2 am (your organization's time zone). Items with changes older than 30 days get trimmed to their last 1000 changes (if there are more than 1000 changes).

That means the last 1000 changes for every Work Item, dependency, and resource assignment will always be stored and visible from the Project they are in. 

Work Item changes are aggregated to the Project they are in. They don't get rolled up to parents, grandparents or Program.

Using Project Change History, you can select multiple Projects and generate an aggregation of all changes in the last 7 days to all Projects you manage, for example.

    Can end users have the ability to create a report that can pull in specific data field changes from the project change history? Today we have to leverage custom data fields and work flow rules to create custom change logs to track changes to key project data fields. If there was a option for us to link our project data table to the change history table in the Reports module then we would be able to create reports that would give use the information we need without having to use custom data fields and workflow rules.
