Automatically generate a map source hierarchy

A map source hierarchy is a data source that is used to create a map report. Except for the top-level wrapper, each map source level in the hierarchy defines the data for one map drill level.

Before you begin

Role required: report_admin or admin

About this task

Note: A set of predefined map sources and maps are available by default. Use these predefined objects whenever possible. If you need a map source that does not exist, generate it automatically using Generate map source levels link on the map source form, then customize it. You can automatically generate map source levels only for map sources that reference the location table. These map sources have a field that ends in .location.


  1. Navigate to Reports > Administration > Map Sources.
  2. Click New.
  3. Fill in these fields.
    Table 1. Map Source fields
    Field Description
    Name Enter a descriptive name. For example, Incident by location. Users select the map source by this name in the Map data field when they create a map report.
    Table Select the table that contains the field that you want to map. All map source levels in the hierarchy use this table.
    Field Select the field with the data that you want to display on the map report. This field must reference the location table. For example, incident.caller.location or incident.location. You can dot walk to this field.
    Active Select this check box to make the map source available when creating map reports.
  4. Right-click the form header and select Save.
  5. Click Generate map source levels.
    Three map source levels are created. Only the level 1 map source is visible in the Map Sources related list.
    Note: A map source can have up to four levels, but only three are automatically generated. If the map hierarchy you are using requires an extra drill level, you can create a fourth level map source.

What to do next

The map source is ready to use in a map report.
