Prevent issue assignment based on field value

[Mario P]

For HR I would like to implement an automation rule that prevents the issue being assigned to the same user that it is targeting.

Scenario:

User has complaint against HR employee that handles JSM tickets. If they make a ticket I would like to prevent this ticket to be assigned to that user(target) so that there is no conflict of interest.

What I tried:

When Issue is assigned

Compare if account ID is NOT the same as target account ID

Then set issue to Unassigned.

However I am having trouble with obtaining the information from a field called: Party name.

Is the field Party Name a user type field? And does it have the space in the name or not? If it has a space you have to use the space in the smart value as well or use the customfield_xxxxx instead.

Goodmorning,

Good questions.

The field looks like this:

And judging by the Aa indication it is probably a user type field:

Instead of naming it I could identify it with it's custom field ID? That's probably in Issues > Custom fields > Field name > edit details > copy id from URL correct?

On another note, is the logic sound? To leave it unassigned might not be preffered I would rather assign it to someone except the for the target.
