What is a change request?

[SNnewbie2]

I'm trying to understand the concept of change request? what is it ? and why do we want to create a change request. Thank you.

This code is using a variable named "select_add_remove_or_modify" to determine what type of DNS change was requested in Service Catalog. Depending on what type of change was selected, lines 31-42 determine what change_request record will be used as a kind of template to be copied. It uses the sys_id (unique identifier field) of each change_request to determine what template is going to be used. The "add" template is used by default. If you want to see these template records just attach the following to your instance URL:

/change_request_list.do?sysparm_query=sys_idINfe7b74ac2b6f3100954cbd63e4da159e,be7b74ac2b6f3100954cbd63e4da159f,7e7b74ac2b6f3100954cbd63e4da15a0

Line 45 makes a call to a Script Include named "TaskCopy". The copyChange method in the "TaskCopy" script include makes a new copy of whatever change request template corresponded to the value selected in the "select_add_remove_or_modify" variable (i.e. "add", "remove" or "modify").

The "TaskCopy" API is not an out-of-box ServiceNow API so I can't tell you exactly how it works - I am just making inferences. However, you can see the Script Include code (assuming it is one, but I'm pretty sure it is) here:

/sys_script_include_list.do?sysparm_query=name%3DTaskCopy

P.S. Here are some really helpful scripting references

Hi claudilla, please watch this recorded webinar to understand it well. : Change Management: How to get up and running quickly

A change request a statement in the form of a declaration., i.e. it states what needs to be accomplished.

In a wild it is often used as a means of communicating activities.

It is best to have a look at the ITILv3 documentation to understand the interaction between all the processes.

Hi,

Change request is used to track all the changes made in the IT environment of the organization.   For all changes which affect IT or departments which rely on IT Change request is created.
