The following article describes how to populate the contact fields Support1, Support2, and Support3 for a CI with the GRLoader, including the syntax for an XML input file
Release: 12.9 and higher
CA Service Desk Manager
You must use the following syntax:
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<GRLoader>
<ci>
<name>CI_name</name>
<class>class_nem</class>
<support_contact1_uuid>contact1_last_name, contact1_first_name</support_contact1_uuid>
<support_contact2_uuid>contact2_last_name, contact2_first_name</support_contact2_uuid>
<support_contact2_uuid>contact3_last_name, contact3_first_name</support_contact3_uuid>
</ci>
</GRLoader>
As you can see you must use the combo name of the contact. If the contact is a group simply use the group name.
