# Control when Views update with Auto-sync

> Turn Auto-sync on or off for a Mammoth View and its destinations, read the Failing, Out of date and Sync off chips, and release pending data in Monitor.

Auto-sync decides whether new data flows into a View, and out of it to its destinations, without anyone acting. Turn it on or off from the View's **Auto-sync** menu item, or in the data editor under **More Pipeline options** > **Auto-sync options**. Changing it needs edit access to the project; it is disabled in a View-only workspace.

For the rest of the View Settings menu, see [Views: create, rename and delete](https://mammoth.io/docs/learn/organise/views/).

## How Auto-sync works

**Auto-sync** is a setting on each link between a View and the data it receives or sends. It controls whether data passes along that link automatically.

- **Auto-sync ON**: new data passes along the link, and the View reruns without action.
- **Auto-sync OFF**: data stops at that link. On a View's incoming link, the View is not rerun when its dataset receives a new batch, and the new batch stays pending until you release it.

The Auto-sync controls may not be available in every workspace.

Turn Auto-sync off for Views that feed compliance or executive reports, where output should be reviewed before delivery. Turn it off for Views connected to production systems, where an unchecked pipeline change should not spread, and anywhere a person needs to approve data before it reaches its destination.

### Turn Auto-sync on or off for all of a View's links

1. Open the View in the data editor.
2. Select **More Pipeline options** in the pipeline toolbar.
3. Select **Auto-sync options**. The dialog has two tabs: **Incoming data** (the sources the View receives data from) and **Outgoing data** (the destinations the View sends data to).
4. Each row shows the source or destination, its type, the last sync and the Auto-sync state (ON or OFF). Tick rows and select **Enable auto-sync** or **Disable auto-sync**.
5. Select **Apply changes**.

You can also turn a single View's incoming Auto-sync on or off from its menu (**Auto-sync**).

### Turn Auto-sync on or off for one destination step

Each step that sends data out of the View (Send to Dataset and other export steps, and dashboard steps) has its own Auto-sync switch. Open the step's **More options** (three-dot) menu in the Pipeline panel. The **Auto-sync** toggle sits at the top of the menu.

The step card's footer shows the state, **Auto-sync ON** or **Auto-sync OFF**. Hover it for details. On a Send to Dataset step that feeds another View, ON reads "Destination view is automatically updated through this view."

| Step | When the toggle is limited |
| --- | --- |
| Export step | Shown only once the step has run. Hidden while the step is being reordered, or while Draft mode has changes that are not applied yet. Disabled in a View-only workspace and while Draft mode is applying changes. |
| Dashboard step | You need edit access to the dashboard to change it. |

To hold every destination while you edit and check a change, use [Pause sends while you edit](https://mammoth.io/docs/learn/clean-and-shape/pause-sends/) instead of switching steps off one by one.

### Release data held while Auto-sync is off

When a View's incoming Auto-sync is OFF and its dataset receives a new batch, the View does not rerun. The batch is held as pending in **Monitor**, on the **Needs Attention** tab, and the item reads "new batch received, auto-sync off".

To release pending data:

- **From Monitor**: go to the **Needs Attention** tab and select **Process** on the item (use **Preview** to look at the batch first). For a pending update to a destination, the main button is **Update**.
- **From the pipeline panel**: open the three-dot menu on the Send to Dataset task card and choose **Run now**.

Monitor also has a **Paused** tab that lists items paused through Auto-sync controls. Select **Turn Auto-sync ON** there to resume them. See [Activity log](https://mammoth.io/docs/learn/automate/activity-log/).

## What the View status chips mean

In the Data Library, turn on **Show views** under **List settings** to list the Views of each dataset that has more than one. The **Status** column of a View's row shows a chip when the View needs attention:

![Data Library list with a View Settings menu showing Open and Settings items](https://mammoth.io/docs/images/20260326_102631_Datasetoverview.webp)


| Chip | Meaning |
| --- | --- |
| **Failing** | The View's pipeline hit an error on its latest run. |
| **Out of date** | New data is pending for the View and hasn't been processed yet. |
| **Sync off** | The View's Auto-sync is OFF, so new data is held until you release it. |

The dataset's own row adds these up, for example "1 failing" or "2 batches behind". When you open a dataset, its panel names the problem in a banner, such as "A task failed on the last run." or "Auto-sync is off, so this view stays frozen when the dataset refreshes."

### Data may be inconsistent

Inside the data editor, the bottom bar shows the same problem as a warning chip. When a View has data updates waiting, it shows a yellow **Data may be inconsistent** chip with a warning icon. Its tooltip reads "Check Dataflow Monitor to manage Pending data updates."

Click the chip to open Monitor with this View highlighted. Process or update the pending items there, and the chip goes away.




## Troubleshooting

| Symptom | Cause | Fix |
| --- | --- | --- |
| Destination not updating although the pipeline runs | Auto-sync is OFF (a crossed-out sync icon shows in View Settings), so the output is held. | Open Monitor, go to **Needs Attention**, and select **Process** (or **Update** for a pending destination update). Or turn Auto-sync ON. |
| **Data may be inconsistent** in the data editor | The View has data updates waiting. | Click the chip to open Monitor, then process or update the pending items. |
| **Failing** chip on a View | The View's pipeline hit an error on its latest run. | Open the View and fix the highlighted task. See [Fix a failing step](https://mammoth.io/docs/learn/clean-and-shape/fix-a-failing-step/). |
| The Auto-sync toggle is missing on an export step | The step hasn't run yet, it is being reordered, or Draft mode has changes not applied yet. | Run the step, or apply your Draft mode changes. |
