# How to get the number of records imported in Custom data import using Custom fields

When using Custom data import to import log or entity type dimension-only data, you might want to build reports that show the number of records. For example, when importing Leads from your CRM, you may want to create a dashboard that shows the number of leads in each status of your funnel.

You can achieve this by importing the data first and then using [Supermetrics Custom fields feature](https://docs.supermetrics.com/docs/about-supermetrics-custom-fields) to create the metrics.

## Instructions

### Step 1: Create the import

Create an import for your data using Custom data import. If you’re unfamiliar with creating an import, [take a look at our guide to configure the import](https://docs.supermetrics.com/docs/how-to-configure-a-data-import-for-custom-data-import).

### Step 2: Create the Custom field

1. Go to Custom fields to create a new field.
2. Create a new Custom field.
3. Select **Metric** as the field type.
4. Select **Custom data import** as the source.
5. Select the import you want to use from the **Select report type** dropdown.
6. Define the settings for your custom field:
  1. Select **Function** as the transformation type.
  2. Select **Convert data type as** the function.
  3. For the Value, select a field from your import that resembles a unique identifier for the item you want to count, for example, Lead ID. Please note that if your imported data does not contain any unique identifier, you can use the Supermetrics-generated Row ID field to count values.
  4. Select **Integer** for the Data type,
  5. Select **Static value** as the default and enter a value of **1**.
  6. Click **Next**. ![Creating a custom field with data source and transformation options in a software interface.](https://cdn.document360.io/a13cead5-eaae-456f-9bd1-0941d590c0e3/Images/Documentation/convert-data-type-integer.png)
7. Give a name and description for your custom field.
8. Open **Advanced settings**.
9. Select **Integer** as the Output data type.
10. Click **Create custom field**.

Now you can use your newly created custom field in any Supermetrics product to query the number of records imported.
