Drill-Down
You use this function to refine the data the system displays to get a more detailed view during analysis.
A company receives an increasing number of quality notifications and a product engineer analyzes the reason. As the first step, she displays the number of quality notifications over time. Then she becomes interested in finding out the damage code to find out the reasons. Based on this, the engineer can pick up the most frequent code and try to find out by using the sales orders the plant that delivered the faulty parts. Another option could be that she directly wants to view the content of a quality notification.
Drill-down in a more technical sense means the execution of consecutive queries views, or the same query view, based on the context.
You can perform a drill-down in BCV if one of the following conditions applies:
You have enlarged a quick view from the side panel, or executed a query view from the query view hierarchy.
The queries whose query views you want to drill-down into have a meaning assigned to them. For more information, see Definition of Meanings.
You have set up Launchpads for drill-down. For more information, see Defining Launchpad Applications in BCV.
When you click an existing link (may also be a point or bar in a chart), and the corresponding field has a meaning assigned to it, then the system displays a list of available navigation targets.
The system retrieves the relevant navigation targets (query views, launchpad applications) according to the set of meanings, which consists of the meanings available up to the time of the drill-down, and the meanings transferred with the drill-down. For the first drill-down the navigation targets represent the context transferred by the application using BCV, along with the chosen meaning. A valid navigation target has at least each of the transferred meanings as selection parameter.
If you select one of the navigation targets the system displays in a dialog box, then the system calls the target with the transferred set of meanings and its actual content. If more input fields are necessary than provided by the transfer, the system tries to retrieve these fields from previous drill-down steps. If this is not sufficient, the system displays a dialog box, asking you to fill in the mandatory input fields.
Query views
The output fields of the underlying query can serve as post selection filters. To achieve this, you have to define an appropriate query input field, and link it to the search connector output field by means of a selection criterion.
The system adds a breadcrumb in the header for navigation and orientation purposes. Additionally, the system provides a hierarchy of query view drill-downs executed so far, in the Drill-Downs accordion item of the side panel.
