# Drill Through

The **Drill Through** feature allows users to explore data in greater depth by drilling into a **specific dimension value** from a saved View. It provides contextual insights by dynamically updating the View to reflect the selected drill-through dimension. This enables users to move from high-level summaries to detailed, dimension-specific breakdowns.

### Steps to Use Drill Through

1. Navigate to the **final screen** of a Report.
2. Select a **View** that includes at least one Dimension.
3. Click the **ellipsis (⋮) icon** for the selected View.
4. Choose **Analyse** to open the View in analysis mode.

#### Performing Drill Through

1. In the **Analyse window**, left-click on a column containing a **data value**.
2. A **context menu** opens.
3. From the menu, select **Drill Through**.
4. A list of related drill-through options appears.
5. Select the desired option to drill through.

* The View dynamically updates to reflect the chosen drill-through perspective.

### Example

* A saved View displays **skill-based USD billing** (BizViz, SQL, Algorithms).
* The user selects **Source-wise Drill Through**.
* The updated View now shows the **sum of USD billing by Source** for the selected skills.

### Refining Drill Through

* To switch to another drill-through dimension:
  1. Use the **drop-down menu** next to the currently applied dimension.
  2. Select another Dimension from the context menu.
  3. The View updates based on the newly selected dimension.

**Example:**

* Switching from *Source-wise* to *Previous Organization-wise* drill-through updates the View to show **USD billing grouped by Previous Organization** for the same skills.

### Returning to Original View

* To exit Drill Through, click the **Close icon** next to the selected Drill Through option.
* The View reverts to its **original display**.

### Best Practices

* Use Drill Through on Views with **multiple dimensions** for richer exploration.
* Apply **filters** before drilling through to focus on the most relevant subset of data.
* Combine **Drill Through** with **Drill Into (time-based)** to analyze both contextual and chronological perspectives.
