# Create Components for Forecast Pages

Create custom Aura components that are available to add to Lightning forecasts pages.

To add a custom template to a Lightning forecasts page, implement the `lightning:forecastingTemplate` interface.

To allow the component access to a Lightning forecasts page, implement the `lightning:availableForForecastingPage` interface.

Upon initialization, the component attempts to populate the following attributes to provide some forecast context. The attributes include:

-   `contextPeriodIds`—The time period IDs from the user context.

    ```nolang
    <aura:attribute name="contextPeriodIds" type="String[]" />
    ```

-   `currencyIsoCode`—The ISO code of the unit of currency that the user views.

    ```nolang
    <aura:attribute name="currencyIsoCode" type="String" />
    ```

-   `forecastingOwnerId`—The forecast owner's user ID.

    ```nolang
    <aura:attribute name="forecastingOwnerId" type="String" />
    ```

-   `forecastingTerritoryId`—The forecast territory's ID.

    ```nolang
    <aura:attribute name="forecastingTerritoryId" type="String" />
    ```

-   `forecastingTypeId`—The user’s selected forecast type.

    ```nolang
    <aura:attribute name="forecastingTypeId" type="String" />
    ```

-   `scope`—The supported scope type. If `scope` is undefined or null, a single territory or role page is loaded.

    ```nolang
    <aura:attribute name="scope" type="String" />
    ```

    ```nolang
    SupportedScopeType  : {'my_territory'}
    ```


Lightning forecasts pages don’t support any standard or custom events published from custom components.

When the Lightning forecasts page changes, such as owner or forecast type, the page header publishes a Lightning message. You can subscribe to the `lightning__forecasting_flexipageUpdated` LightningMessageChannel to update your custom components based on Lightning forecasts page header changes.

**note:** To ensure that custom components appear correctly, enable them to adjust to variable widths.
