# Getting started with the audit log

:::info
This feature is reserved for customers with an Enterprise license.

:::

:::info
How do I get to the audit log? In the sidebar, under "Administration", click "Audit log".

:::

The audit log records changes to master data, permissions and settings in easyreview. You can trace who made which change, and when.

The feature serves as a security tool: you can check whether, for example, access rights or the [options of a review](/en/c/feedbacks/configure-review-options) were changed without authorization.

## Requirements

To access the audit log you need the "Audit log" access permission. It is set up on request by the contractual contact person of your company through [easyreview support](mailto:kontakt@easy-review.de?subject=Anfrage%20Zugriffsrechte%20zur%20Revisionshistorie).

## Open the overview

1. In the sidebar, in the "Administration" area, click "Audit log".
2. You see a table of the most recent changes.

 ![Navigation to the audit log](/attachments/revision/erste-schritte-revision/revisionshistorie-navigation.png)

The table shows the following columns:

* **Timestamp**: when the change was made
* **Action**: the kind of change (created, changed, deleted) and the type of data changed
* **Affected**: the changed record, e.g. a link to the affected employee or feedback
* **Changes**: which data fields were changed
* **Operator**: who made the change. For changes made by easyreview support, "easyreview Team" appears.

:::info
By default, the changes of the last 2 years are shown.

:::

## Recorded object types

The audit log records changes to the following object types:

* **Employee**: master data, access rights and custom fields
* **Feedback**: title, reminder intervals and options such as sealing or diplomatic status
* **Participant answer**: changes to answer values in feedbacks
* **Target agreement**: recipient, name, visibility and reminder settings
* **Key result**: title, description, progress and weighting
* **Target agreement process**: title and completion settings
* **Target agreement edition**: name, period and associated target agreement process

## Filter

You can narrow down the changes shown:

1. In the "Timeframe" area, set the start and end date you want.
2. In the "Object type" field, choose which kind of changes you want to see (e.g. only employees or only target agreements).
3. In the "Operator" field, choose the employee whose changes you want to narrow the display to.
4. Click the funnel icon to apply the filter.

In the "Operator" field you can type parts of the name. The list shown is filtered automatically.

## View the details of a change

1. Open the overview page of the audit log.
2. Click the timestamp of the change you want.

 ![Clicking the timestamp of a change](/attachments/revision/erste-schritte-revision/revisionshistorie-zeitpunkt-klicken.png)

The detail page shows:

* **Revision ID**: a unique technical identifier for the change
* **Timestamp**: the exact time of the change
* **Action**: the kind of change and the type of data changed
* **Affected**: the changed record
* **Operator**: who made the change

In the "Changes" section you see a table with the columns "Data field", "From" and "Changed to". Each row shows one changed field with its old and new value.

:::info
The export respects the filters you have set. All available changes in the selected period are exported. Exporting large periods can take a while.

:::

## View the changes for a single employee

You can open the audit log for a specific employee directly from the employee profile:

1. Open the [employee profile](/en/c/general/employee-profile) of the employee you want.
2. Click the "Details" tab.
3. Click "Show audit log" at the bottom of the Details tab.

 ![Show audit log in the employee profile](/attachments/revision/erste-schritte-revision/revisionshistorie-mitarbeiterprofil.png)

You then see a filtered view of the audit log that contains only changes to this employee.

:::info
Additional filtering is not possible in this view, otherwise the restriction to the chosen employee would be lost.

:::

## View the changes for a feedback

You can also open the audit log for a specific feedback:

1. Open the [participant list of a review edition](/en/c/feedbacks/participant-list).
2. Click the three dots in the top right of the participant list.
3. Click "Show audit log".

You then see only changes to this feedback.

:::info
Here too, additional filtering is not possible, otherwise the restriction to the chosen feedback would be lost.

:::

## Paging

At the bottom of the page you find the page navigation, which lets you page through to older changes.
