# Develop function class

You can use a function to fill the related value of a condition.

You can use function for a condition on:

- An event procedure action.
- A query range or a configurable grid query range.

For a function, a class is required. To develop this class, extend the DAWFunctionRun class.

**Prerequisite**: Develop the extension of the DAWFunctionRun class in the AOT before you start the steps.

> [!NOTE]
> **Note**
> 
> The steps are to have the developed function class uploaded as function to the related library.

### Steps

1. Click **Mobility design**.
2. Click the **Libraries** tab.
3. In the list, find and select the desired record.
4. Click **View**.
5. Click the **Functions** tab.

> If you deploy (export/import) an application as built in Mobility studio, make sure the related custom function classes are deployed as well. You can do so with a Microsoft Dynamics Lifecycle Services project.
