# Adding data to your table

When you drag and drop a *Qommentary Writeback* extension to your sheet, you will be prompted to select Dimensions and Measures. 

Adding dimensions and measures works in the same fashion as native Qlik Sense charts. 

{% hint style="warning" %}
A minimum of **one (1) dimension** is required for the extension to be initialized.
{% endhint %}

Additionally, the following *Qommentary Writeback* properties are available:

### Dimensions
