# Creating a Month List

In preparation for adding formulas to our workviews we will need a hierarchy which acts as an ordered list of months. We will feed this list into a Sequence function in our formula which rolls the prices.

From our model page, click **Dimension → Month** and then add a new hierarchy named **Month List**.

```js
Jul
Aug
Sep
Oct
Nov
Dec
Jan
Feb
Mar
Apr
May
Jun
```

Now we can create our rolling and override price formulas in the next section.
