### Open the Virtual Attributes section

### Enter the name of the new virtual attribute

{% hint style="info" %}
By default, you will be in "Create New Attribute" mode. After you finish creating a virtual attribute, you can select an existing virtual attribute to edit in that top dropdown to make any updates as needed.
{% endhint %}

### Add the description of the virtual attribute

This description will be used in the semantic model for the attribute.

### Select the source data type

### (Optional) Select the W Question Category

You can select one of the W (What, Where, When, Who, Why) Question categories. This value will be used to determine which section of the semantic model to add the attribute to.

### (Optional) Select the Object Array

The object array the virtual attribute will be inserted into. If left blank the virtual attribute will be inserted at the root level.

### Enter the SQL Expression

This SQL expression will be used for the Dynamic Table column definition.
