Can we use the INRDID field on ca_contact table?

Products

• CA Service Management - Service Desk Manager

Issue/Introduction

Issue:
=====
Would like to know if we can use the "inrdid" column from ca_contact table for other integration or customization purposes.

Steps:
======
-> The field is mentioned as below in documentation (https://techdocs.broadcom.com/us/en/ca-enterprise-software/business-management/ca-service-management/17-3/reference/ca-service-desk-manager-reference-commands/data-element-dictionary/contact-ca-mdb.html):

inrdid INTEGER   Identifies the role ID.

-> Noted that this field is not present in ddict.sch , also via WSP creating new zfield on cnt object is creating in usp_contact table and not in ca_contact.

Environment

Release : 17.2

Component : SERVICE DESK MANAGER

Resolution

Discussed with SE via defect - DE61880. 
As per SE review it is advised not to use INRDID field or any other internal field.

It is advised not to customize the ca_contact table as it is a common table which is shared across many other products in Broadcom, hence even via WSP it doesn't give option to add new field to this table but to extension table usp_contact.
