# How to Create a Forecast

Quickly build a 12 month forecast by leveraging our AI models, with just a couple of clicks. Let's get started below!

{% hint style="danger" %}
In order to start creating your first forecast, please ensure that your master product list has been uploaded to Moselle. For more information [click here](/operations/catalog/adding-products/import-your-items.md).
{% endhint %}

{% hint style="info" %}
Note: You may see the term "Scenario Plan" in some parts of Moselle. This is a legacy name that refers to forecasts.
{% endhint %}

### Creating a New Forecast

Forecasting runs on Mo — Mo takes you through the whole process, from your first plan to a polished forecast.

#### Navigation

1. Select **Forecast** from the left hand sidebar.
2. Click the **+ Create Plan** button.
3. Follow the wizard to create your forecast.

#### Setup Steps

1. Fill in the **Plan Name** field (e.g., "November Plan")
2. Set the **Coverage Period** — a start and end date for the forecast
3. Click **Next**
4. On the next step, choose how to build your forecast:
   * **Top down** — set revenue targets and Mo converts them to units. See [Generate a Top-Down Forecast](/planning-and-execution/forecasting/phase-2-build-your-forecast/how-to-create-a-forecast/generate-a-top-down-forecast.md)
   * **Bottom up** — let Mo build your plan from your past sales data using an AI model. See [Generate a Bottom-Up Forecast](/planning-and-execution/forecasting/phase-2-build-your-forecast/how-to-create-a-forecast/generate-a-bottom-up-forecast.md)
   * **Start blank with Mo** — skip generation and build the forecast from scratch together with Mo in a chat thread
   * **I already have a forecast — upload it** (link at the bottom of the step) — hand your existing file to Mo directly; Mo imports it and helps you refine it, rather than mapping it to a fixed template

{% hint style="info" %}
**Tip:** For most catalogs, Top down or Bottom up gets you a usable 12-month forecast in minutes. Use **Start blank with Mo** or the upload link when you'd rather build the plan conversationally instead.
{% endhint %}

### Manually Uploading a Forecast

You can export an existing forecast, make manual adjustments, and re-upload it to Moselle.

#### Export Your Forecast

1. Navigate to your Forecast page
2. Click the **Gear Icon**
3. Select **Export / Download**
4. Check your email for a file named `projections_[...].csv`

#### Edit the Exported File

When editing the exported file, keep these guidelines in mind:

* **Keep these columns intact:** `scenarioPlanId`, `itemId`, `channelId` — these are required for the upload to work correctly
* **You can delete:** Any rows or date columns you don't need
* **Important:** Do not change the date format in the month columns (keep it exactly as exported)

#### Upload Your Changes

1. Make your edits to the forecast values
2. Save the file
3. Upload the file back into Moselle through the forecast upload interface
4. You will receive a **push notification** when the upload is complete

### Modifying an Existing Forecast

You can adjust settings and regenerate your forecast without creating a new one.

**Access Forecast Settings**

1. Navigate to your Forecast page
2. Click the **Gear Icon** at the top right corner
3. Select **Modify Forecast**

**Adjust Revenue Targets**

Update revenue goals for specific sales channels. This is particularly useful when:

* You need to update goals for newly split channels (e.g., Amazon USA vs Amazon Canada)
* Your original revenue goals were set before channel splits occurred
* Revenue targets have changed since the forecast was created

**To update revenue targets:**

1. Click **Gear Icon** → **Modify Forecast** → **Adjust Revenue Targets**
2. Enter updated revenue goals for each channel
3. Click **Regenerate** to update the forecast with new targets

{% hint style="info" %}
**Common Issue:** If you created revenue goals before channels were split (e.g., when Amazon was one channel instead of Amazon USA and Amazon Canada), your goals may only appear for one of the split channels. Update revenue targets for all channels and regenerate to fix this.
{% endhint %}

### Managing Your Forecasts

#### Navigation

Your list of active forecasts appears on the Forecast landing page. You can navigate between your **Master** forecasts and **Previous** forecasts.

#### Forecast Details

Each forecast displays:

* Forecast name
* MAPE score
* Author who created the forecast
* Creation date
* Last updated timestamp

#### Forecast Actions

Click the **three dots (⋮)** on any forecast to:

* **a)** View and Edit
* **b)** Duplicate
* **c)** Archive

{% hint style="danger" %}
**Warning:** Archiving a forecast will remove it from the list indefinitely.
