When managing your team's schedule in Assembled, you may occasionally need to undo changes, whether from a template application, a bulk edit, or an optimization that didn't work as expected. Scheduling history lets you restore a previous version of your staffing timeline without contacting support.

## How do I restore a previous version?

1. Navigate to the [**Staffing timeline**](https://app.assembled.com/staffing/timeline).
2. Select **Show scheduling history** above the timeline grid.
3. Browse the version history to find the restore point you need. Typically the version immediately before your unwanted changes.
4. Select **Restore version** next to that timestamp.
5. Confirm the restoration.

The timeline will refresh automatically when the restoration is complete.

Keep in mind: Restoring a version reverts _all_ changes made since that point, not just the most recent edit. Manual edits, optimizations, and other modifications made after that timestamp will also be undone. For larger teams (200+ agents), the restoration may take 30–60 seconds.

## How do I restore changes for specific agents only?

If you only need to roll back changes for a subset of your team, filter the timeline first before restoring.

1. On the staffing timeline, select **Add filter** and apply filters to show only the agents you want to restore.
2. Select **Show scheduling history**.
3. Find the version you want to restore.
4. Select **Restore version**. This will only affect the agents currently shown on the timeline.

For example, if you applied a new template to your entire support team but only the night shift needs to revert, filter to night shift agents first, then restore.

## What if I can't restore a version?

If you see an error about conflicting edits, there are a couple of approaches depending on what you need to undo.

**Re-apply a previous template**

If you only need to undo a template application and want to preserve manual edits made afterward:

1. Go to **Configure >** [**Templates**](https://app.assembled.com/settings/templates).
2. Find the template that was applied before your unwanted changes.
3. Re-apply that template to your staffing timeline.

Keep in mind: Re-applying a template preserves manual edits made after the original template was applied, but does not restore other manual changes or optimizations.

**Contact support**

If you're still having trouble or need help with a complex rollback, reach out to [support@assembled.com](mailto:support@assembled.com) and include the version timestamp you're trying to restore.

## How do I check what changed?

Each version in scheduling history shows the timestamp of the change, who made it, how many agents were affected, and the type of change, such as a template application, manual edit, or optimization. Select **Show scheduling history** on the staffing timeline to browse this information.
