Extending table

[Hafsa1]

I have a requirement to extend table "sn_customerservice_case" to 6 child tables like payroll, HRservice, NAprocurement, EUprocurement etc..

What is the best practice as per ServiceNow to extend CSM table?

Shall I create as "x_csm_payroll_case"? or like below

"sn_customerservice_case_payroll"

"sn_customerservice_case_hrservice"

[Hafsa1]

Table name  is coming with prefix "sn_customerservice"

Extending/child classes will inherit the field and Prefix from the parent table, unless overridden by a different Prefix defined on the child table.
