How to: Drill Through to Case Data from a Mining Model

If a mining model has been configured to let you drill through to model cases, when you browse the model, you can retrieve detailed information about the cases that were used to create the model. Moreover, if the underlying mining structure has been configured to allow drillthrough to structure cases, and you have the appropriate permissions, you can return information from the mining structure. This can include columns that were not included in the mining model.

If the mining structure does not allow you to drill through to the underlying data, but the mining model does, you can view information from the model cases, but not from the mining structure.

NoteNote

You can add the ability to drillthrough on an existing mining model by setting the property AllowDrillthrough to True. However, after you enable drillthrough, the model must be reprocessed before you can see the case data. For more information, see How to: Enable Drillthrough for a Mining Model.

Depending on the type of viewer you are using, you can select the node for drillthrough in the following ways:

Viewer name

Pane or tab name

Select node

Microsoft Tree Viewer

Decision Tree tab

Click a tree node.

Note   Avoid using drillthrough on the All node, because it may take a very long time to return results.

Microsoft Cluster Viewer

Cluster Diagram

Click a cluster node.

Microsoft Cluster Viewer

Cluster Profiles

Click anywhere in cluster column.

Microsoft Association Viewer

Rules tab

Click a row that contains a set of rules.

Microsoft Association Viewer

Itemsets tab

Click a row that contains an itemset.

Microsoft Sequence Clustering Viewer

Rules tab

Click a row that contains a set of rules.

Microsoft Sequence Clustering Viewer

Itemsets tab

Click a row that contains an itemset.

NoteNote

Some models cannot use drillthrough. The ability to use drillthrough depends on the algorithm that was used to create the model. For a list of the mining model types that support drillthrough, see Using Drillthrough on Mining Models and Mining Structures (Analysis Services - Data Mining).

To view drillthrough data from a mining model

  1. In Business Intelligence Development Studio, open the mining structure that contains the mining model you want.

  2. In Data Mining Designer, click the Mining Model Viewer tab.

  3. Select the model from the Mining Model drop-down list.

  4. Select a viewer from the Viewer drop-down list, and right-click the specific node.

  5. Select Drill Through, and then select either Models Columns Only, or Model and Structure Columns to open the Drill Through window.

  6. To copy the data to the Clipboard, right-click any row in the table, and select Copy All.
