# Check a pipeline and send an output from your phone

> On a phone, open a Mammoth View's Steps to check pipeline health, see the data after any step, add a note, send an output with Run now, and switch draft mode.
>
> Applies to: Roles: Notes, sends and draft mode need edit access; a view-only workspace can read the steps only. Where: View on a phone › Steps

On a touch phone, the **Steps** button under a View's title opens its pipeline: the source, each step in order, and the **Outputs** the View sends data to. You can check health, look at the data after any step, add notes and send an output, but you can't add or change steps on a phone. In a view-only workspace, you can read the steps but can't write notes, send outputs or switch draft mode.

## Read the pipeline's health

The sheet's subtitle sums up the pipeline's health:

| Status | Meaning |
| --- | --- |
| **Up to date** | Nothing needs a look |
| **Pipeline running** | The pipeline is still running |
| "2 steps need a look" | Steps with an **Error**, a **Check failed**, or a checkpoint that **Needs approval** |
| "1 output out of date" | An output has not received the latest data |
| "3 draft changes not applied" | Someone has draft changes waiting |

A step card is marked when it needs a look. A data check shows how many checks failed, for example "1 of 3 checks failed".

When there are draft changes, the rows you see are the applied pipeline's, not the draft's. A notice under the title says how many draft changes are waiting. Review them on a computer.

## Open a step and add a note

Tap a step to open it. The sheet shows the step's rule, the problem if there is one, the **Columns changed** (**Added** or **Changed**), **Rows after**, who added it and when, and its **Note**. Write or edit a note with **Add note**. A note is a comment saved with the step and does not change the data.

Where the data editor would offer to add a task, the list reads "To add or change steps, open this view on a computer."

## See the data after a pipeline step

1. In a step's sheet, tap **See the data after this step**. The rows screen shows the data as it stood after that step, for example "After step 2 of 5 · Filter".
2. The columns the step changed come first and are tinted. Tap **Only its column** (or **Only its 2 columns**) to show only those.
3. Use the arrows to move one step back or forward, or tap **Latest** to return to the current data.

Your Explore cards follow the step you're looking at. Metrics are not shown while you look at an earlier step.

## Send an output now from a phone

An output that can be sent now shows a **Run now** button, on its card and in its sheet.

1. Tap **Run now**.
2. Check the confirmation: "Send the latest data to" the destination, and "You can't undo a send."
3. Tap **Send now**.

If it fails, you see "Couldn't send. Try again, or open the view on a computer."

**Run now** is offered only when the output can be sent: not while it is already sending, while the pipeline has an error, or while there are unapplied draft changes. Live links and outputs with auto-sync on don't offer it.

## Switch draft mode on a phone

When the View has a draft mode setting, the top of the sheet shows **Draft mode** with "Tasks will be pending" or "Tasks will be applied instantly". You can switch it here as on a computer. It can't be switched while the pipeline is running, while a step is failing, or while draft changes are waiting, and the sheet says which.

## Troubleshooting the pipeline on a phone

| Symptom | Cause | Fix |
| --- | --- | --- |
| No **Run now** button | The output is sending, the pipeline has an error, drafts are waiting, or it is a live link or auto-sync output | Wait, fix the error, or apply the drafts on a computer |
| You can't add a note or send | The workspace is view-only | Ask for edit access |
