How to create parent child relationship in service catalog

[Stella5]

E.g RITM10078 is a parent ticket

RITM0089,RITM0097 is a child ticket .

How these ticket will be dependant .

You can have a reference field on RITM table which refers to itself, and when you create the child tickets, make sure you assign the parent ticket sys_id to that reference field.

Its pretty common way of making the parent child relationship in the same table, its in core_company, cmn_location etc

Mark if it is correct or helpful, feedback is appreciated

Hey srikanth ,

How to do that ,

the customer who is working on servicenow .They want to create chid ticket .

On default view of requested item ticket , we dont have any deference field

[ghsrikanth]

You can create a new column sc_req_item with the name Parent Request Item - go to any requested item

Configure -> Table

Enter the column like below

The new field will be available in the default form layout

It will be at the bottom above related lists

So use configure -> form layout to bring it to proper position

Open any RITM for ex: RITM0000001 and put RITM0000002 in the Parent Request Item

Open RITM0000003 and put RITM0000002 in the Parent request item

Then Right Click on header-> Configure -> Related lists

Select the below related list from left sluschbucket, move to right

Open RITM0000002, you will see the child items in the related list
