Removing Transform Template Field Mappings
In the predefined transform templates that ship with Service Board, the code in the Field Mappings field cannot be updated by end users. You can remove these mappings by configuring the _fixed_removed_fields field mapping in the Custom Field Mappings field.
To remove transform template field mappings:
1. In Max Designer, on the Developer Tools () launchpad menu, click Transform Templates, and then in the list view, click a transform template.
2. On the Overview tab, in the Custom Field Mappings field, add valid JSON mapping code for _fixed_removed_fields as shown in the following examples.
To remove field mappings for SVMXC__Problem_Description__c and SVMXC__Priority__c from the Job to WorkOrder Update Template:
{
"payload": {
"fields": {
"SVMXC__Preferred_Business_Hours__c": "payload.fields.svmx_preferred_business_hours",
"SVMXC__SM_Lock_Appointment_Schedule__c": "payload.fields.svmx_lock_appointment_schedule"
}
},
"_fixed_removed_fields": ["SVMXC__Problem_Description__c","SVMXC__Priority__c"]
}
* 
In mapping code, be sure to specify the Salesforce API names for the fields to be removed.
To remove mappings for io_description from the WorkOrder to Job Update Template:
{
"_fixed_removed_fields": ["io_description"]
}
3. In the top left corner, click Save and Close (), and then on the Development Actions () launchpad menu, click Synchronize.
