# Custom Header

We can add a new custom header to the report on columns from the panel on the left side.

![Custom Header](/operational-expenditure-model-figures/workview-custom-header.png)

By double-clicking on the custom heading we can type in a new value to display for each column. Make sure to add double quotes around the text. We will name the first column **LY Actual**.

Second column will be named **Phasing Amount**.

Third column will be named **Phasing Method**.

For our second set we can go through each column and name them. However, naming each individual column for the entire set is inefficient; instead, we could implement a formula that applies to the entire set.

Add the following formula to the header editor and click the **Apply to the Set** and save formula.

```js
IF( ELEMENT("Month")="All Months",
    ELEMENT("Year") & " - " & ELEMENT("Scenario"),
    ELEMENT("Month") & " - " & LEFT(ELEMENT("Scenario"), 3)
)
```

The workview header should now look like the following. In the next section we will hide the uncessary headers.
