Best Practice to follow while adding code to the out of box script include.

[divyasurada]

Hi,

When security incident is created through ITSM incident through a UI action "Create Security Incident", I want to copy some more fields from ITSM incident to the Security incident.

For this, can I directly add the code to the out of box script include or do I have to create a copy of the script include and then add my code to "CreateFromIncident" function?

Please help me with the best practice that I need to follow here.

Thanks,

Divya

Hi 

Best practise says not to ammend the existing functionality because it may have effect on various places.

I would suggest you to create on more function same as this one(different name) and add your lines of code in order to proceed.

Hope this helps.

Hi Omkar,

Thanks for your reply.

Can you also please tell me if I can add the new function to the existing out-of-the-box script include or create a new script include and then add a new function to this?

Hi Divya,

Creating a function in script include won't have any effect because this is your custom function and it won't be called from anywhere else until you call it. So writing it in the same SI would be a good option.

Hi Omar,

During upgrade, this script include will be excluded from upgrade process because this script include will be customized. Is it okay if this happens?

Also can you tell me in which cases we update the existing Script Include/Business rules and in which cases we cannot.

Can you also share a related best practice document by serviceNow if you have any.

Thanks
