# Creating a data type

> Create a custom data type in Pega Dev Studio to hold table values such as invoice line items when building a case for the FlexiCapture connector.

If your case will handle table values (e.g. invoice line items), you need to create a custom data type.

To create a new data type:

1. Open Dev Studio, click the **Data types** tab on the left, click the Explorer menu at the top, and select **Add data type**.
2. In the **Add Data Type** dialog box, type *Line Items* in the **Label** field and click **Submit**.
3. On the **Data model** tab, add the fields that will make up the line items. When you are done, click **Save** to save your changes.
