Pigment tracks all of the data updates done on Blocks (List and Metrics) so that users can see when a change was made and by which user.
Table of content
Block specific view
On List and Metrics, the update history of the Block is available from the icon on the top-right (near the Block settings).

This panel displays all "updates" which have been recorded for that specific Block.
Use the Controller on top of the panel to filter events by Date, User and Action.
Check the "Changes tracked" section, for more details.
Global Update history
To access a global view of all the updates done in an Application, open the History > Updates page.

You can see all of the changes made on all of the Blocks within the Application.
Use the Controller on the top right to filter events by Date, User, Block and Action.
Note
From this page, users can access the history of deleted Blocks.
Updates tracked
Edits (manual input)
All manual inputs on Lists and Metrics are tracked as an "Edit" Action.
On Lists, hover over the update to check which Property and which item was edited (to identify the item, the current "Default Display property" of the item is displayed). If the item of the list has been deleted, no identifier is displayed.

On Metrics, hover over the update to see precisely on which modalities of the Dimensions the update has been made.

Formula updates
All Formula changes are tracked as a "Formula Update" action.

Click on "View changes" to see the old and the new formula:

If some Blocks used in the formula have been renamed after the formula update, the Update History will display an updated version (current version) of the formula with the new Block names. Click on "Show original version" to display the formula exactly as it was when it was updated.

Note
If some Blocks used in the formula are now deleted, the updated version might not be available. In this case, only the "original version" is available.
Import
All CSV imports on Lists and Metrics are tracked as an "Import" Action.

Hover over the summary to see more import details:
- number of item/values inserted
- number of item/values updated
- number of item/values skipped
If the "auto-create missing Dimension item" option is enabled on the import, some dependent Dimensions ( = used by the List/Metric on which the import has been made) might have been impacted by the import. Those changes are flagged by the "Dependent Import" action.
List item deletion
All item deletions on Lists and Metrics are tracked as a "Delete Item" Action.

Block Settings
All Block (Lists and Metrics) changes are tracked as a "Block settings" Action.

Here is the list of tracked events:
- on List and Metric
- Block rename
- Block created
- Block deleted
- Block shared
- on List
- Special Properties updates
- Property creation
- Property deletion
- Property update (type, name or unicity constraint)

Permission to access the update history
To access the Update history, users need to have a Role which grants them the "View Application and Blocks update" permission.
By default only the Admin Role has access to Block and global Update history pages.

Warning
The access right system is not applied to the Update History. For this reason, Pigment recommends granting Update History access users who can access data from the entire App.
