Product Documentation

Note: This feature is not available to installations that use the Apache Derby database. There are limitations within the implementation of the database that preclude this feature from working.

This feature works with Column Reports, Summary Reports, Matrix Reports, Planning Reports and Calendar Reports.

Your administrator may have defined hierarchies for reporting. These allow you to select records at a parent level, and at up to seven child levels for reporting. You may choose to view different fields on a column report for each of the different hierarchy levels, and you may apply different filters to each of the hierarchy levels. In addition, there are functions available that allow you to aggregate the count of the number of issues at each level in the hierarchy.

Note: You must be in the Advanced Query Screen mode to create reports that use reporting hierarchies.

An example of a hierarchy report is that you may want to show a list of all issues by customer, showing details from the Customer business area for each customer, while showing details from the Customer Issues business area for each issue. The following screen shows how this may be set up.

Creating a hierarchical report

First, make certain you are in Advanced Query Mode. Next, you select the hierarchy from the available list of hierarchies within the options section of the report design screen. When you do select the hierarchy, the screen refreshes and you will see a field selection list for each level of the hierarchy, as well as a set of filters to be used for each level of the hierarchy.

The report output will show all the fields selected at all levels of the hierarchy, in the order they appear over all the selection lists.

For each level of the hierarchy, you can apply any filters required for that level in the hierarchy.

Note the checkbox option in the report editor that appears at each level of the hierarchical filters, with the label Include parents without children. If you select this option, parent records will appear on the output, whether or not there are any child records to display. These parent records are suppressed if you do not choose this option.

After following these instructions, you may see a report similar to the next screenshot.

Sample output of Hierarchical Report

Column reports support a special type of hierarchical reporting, called side-by-side hierarchies.  Reporting hierarchies are defined with a chain of descending levels, such in ways such as parent, child, and grandchild levels.  With side-by-side hierarchies, the user can select multiple, independent hierarchies, all with the same base (top) level, and place the results side-by-side on the report output.  For more information, click here.

Aggregation

In the report editor, you can turn on aggregate counting functions for child levels within a hierarchical report. For example, you may want a count of Fixed issues for each customer. This implies that you need to display each customer from the Customers business area and then count the Fixed issues.

Aggregate functions

This may be achieved by a variant of the above report. First, you check the box against the prompt Perform aggregate functions on results. The list of fields at the child level of the query (in this case the Issues level) will clear. Select a field and you may then use your right-hand mouse button to access the output options for the field. In our example, we can count the ID’s with an additional filter of Status = Fixed to achieve the results we would like to see. This selection process may result in a report something like:
