Report basics and concepts
This article introduces the concepts behind reports, which represent one type of 'view' you can create in Dundas BI. Although similar to dashboards, reports are specifically designed to provide a structured way for you to create detailed views involving repetitions of data visualization controls and components.
Reports can be interactive just like dashboards but they are often designed to be simply viewed or exported and printed.

3. Report regions
On a dashboard, you are free to add data items, visualization controls, or components and arrange them anywhere on the canvas. You can also do the same on a report, except that the report canvas contains several specialized regions where you drag-and-drop controls and other items in order to define the content of your report. The purpose of these regions is to allow you to specify a set of controls to repeat, and how you want them repeated. The 'how' part of repeating has to do with hierarchies and levels. For example, the inventory report shown earlier repeats based on a product category hierarchy, where each repetition (of a set of controls) corresponds to a specific hierarchy member (e.g. a product category value such as 'Accessories').
The diagram below illustrates the main regions of a report. You basically drag and drop items onto these regions in Edit mode to build your report. Then switch to View mode to see the actual report consisting of repeated elements.
3.1. Report header and footer
The Report Header region lets you place components that appear just once per report. For example, you can show a title for the overall report here. Conveniently, when you create a new report from the main menu, Dundas BI automatically adds a Label component with the text Title and places it in the Report Header region. Similarly, in the Report Footer region, you can add labels to display a list of references or other information to close off your report.
3.2. Page header and footer
Since a report can span multiple exported pages, the Page Header and Page Footer regions let you add components that are repeated once per page. For example, you can add a label and a separator line to be displayed at the top of each page. Or, you can customize the default labels which show a page number at the top and bottom of each page. These labels (or any other labels) in the Page Header or Page Footer regions support the following keywords in the Label Text property:
- [PageNumber] is replaced with the current page number
- [TotalPages] is replaced with the total page count of the report
3.3. Grouping hierarchy region
The Grouping hierarchy region (Drag a column or hierarchy here...) is the key to specifying how the set of controls added to the Group Body region should be repeated. In the Grouping hierarchy region, you don't add controls or components. Instead, you add one or more columns or hierarchies (or hierarchy levels). For example, you can drag one or more hierarchies or levels that are found under a data connector, data cube, cube perspective, or metric set from the Explore window and drop them onto the Grouping hierarchy region.
In View mode, the Grouping hierarchy region does not appear because it is not a visual element. Instead, the hierarchies or hierarchy levels that you added to the Grouping hierarchy region in Edit mode are now used to repeat the set of controls found in the Group Body region. Specifically, for each hierarchy member value (or combination of values), the set of controls in the Group Body region is repeated once. Additionally, any visualizations within the Group Body region are filtered by the corresponding hierarchy member value (or values). For example, to achieve the repetition of product categories in the inventory report shown earlier, a Product Category hierarchy level is added to the Grouping hierarchy region of the report.
3.4. Group header and footer
The Group Header and Group Footer regions let you place components that appear just once per group. These components are not repeated according to hierarchy values (only the Group Body repeats). For example, in the inventory report shown earlier, Label components are added to the Group Header region in order to display the Qty Left and Unit Price column headings.
3.5. Group body
In View mode, data visualization controls (e.g., charts) and components (e.g., labels) added to the Group Body region are repeated once for each hierarchy member value (or values) according to the hierarchies added to the Grouping hierarchy region. For example, if a Product Category column or hierarchy level is added to the Grouping hierarchy region, and there are 20 such categories in your data, the set of controls in the Group Body region will be repeated 20 times.
4. Child groups
The Child Grouping region lets you add a nested level of repetition in order to create a report that breaks down details further (like the inventory report example where products are repeated within each product category). When you add a hierarchy to this region, four new regions are automatically inserted into the report, forming a child group consisting of:
- a child group header region
- a child group body region (this is the part that repeats)
- a child grouping region (lets you insert another nested/child group)
- a child group footer region
In fact, you can keep on inserting child groups to create deeper and deeper levels of repetition. This allows you to design complex reports that break down details on multiple levels.
5. Sibling groups
When you create a new report, an initial group is added by default. But you also have the option of adding sibling groups which are associated with their own set of grouping hierarchies. Sibling groups are positioned at the same level of the report as the initial group and their repetitions are generated independently.
6. Layout for the example report
The following diagram illustrates a simplified design for the inventory report example. This report repeats visualizations on two levels. It repeats via an initial group that corresponds to the Product Category level, and also repeats via a child group that corresponds to the Product level.
