I recently enabled Tracking History for 3 fields inside the Case object. Even on the workbench in the metadata section of Custom Field, I can see a Case__hd folder where all the fields which are set for tracking are shown.
Now, I am trying to retrieve these __hd files using Metadata API but am not able to retrieve them. The error says
The package.xml which I am using for retrieving these files are
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Package xmlns="http://soap.sforce.com/2006/04/metadata">
<types>
<members>Case__hd.Priority__c</members>
<members>Case__hd.Status__c</members>
<members>Case__hd.Reason__c</members>
<name>CustomField</name>
</types>
<version>34.0</version>
Any idea where I am going wrong..!
