Can someone please explain the meaning of the Affected User field?

Create an Affected User field on Incident. Should it reference sys_user, support multiple values, or derive from
another source? Explain the final design and implement it.

Hi @Singhdeep70 

In ITSM , typically understanding is that

• Caller = person reporting the issue
• Affected User = person actually impacted by the incident

This is just concept.

OOB , there is no such Affected User field provided by serviceNow for ITSM like Incident or Change.  Most of the client/project treats caller_id as Affected user.

Again few clients are there  who have this field "Affected User"  custom field in their call and incident forms.
