CommTrack makes location data available through a fixture. For more details on how to work with fixtures, see: https://help.commcarehq.org/display/commcarepublic/Creating+and+Updating+Fixtures

Configuring Locations: In CommTrack, there is no need to create a fixture for locations. This is done automatically once the user has configured products through Setup -> Manage Locations.

Accessing Locations: When building a mobile application, fixture data can be accessed through the auto-created location fixture on the phone.

Referencing Location Hierarchies in Case List and Details Page

When making a module against supply-point cases, you can reference any location property available in the fixture, as well as any properties of any parents all the way up the chain. To reference a property, you must type a four part code into the case list or details configuration. You need to type this formula in the property box under Display Properties. The format is as follows:

^{location:[my type]:[reference type]/[property name]}

Everything in brackets is something that you replace according to the following table. The colons and slash are mandatory.

location: Just the word "location". This never changes.
my type: The type of the location you expect to be in the case list. This is typically the lowest-level location type, e.g. "outlet". See the "type code" field under Locations (Advanced) in setup to see what to put for each type.
reference type: The type of the location you want to reference. This could be the same as "my type".
property name: The property you want to reference.

The following examples are for a simple hierarchy containing a state, district, block and outlet.

I am a...	referencing my...	Syntax to use

I am a...	referencing my...	Syntax to use
outlet	own type	location:outlet:outlet/location_type
outlet	block name	location:outlet:block/name
outlet	state name	location:outlet:state/name
district	own type	location:district:district/location_type
district	state name	location:district:state/name
