How to automatically assign ticket to user based on the Location of the ticket in JIRA?

[ANN LEE]

Our IT dept need to assign service desk tickets to user based on ticket Location. Is there any way to do that? Someone suggest to use ScriptRunner, but I cannot find any solution. 

Appreciated if you could let me know!

Have a look at the answer in https://answers.atlassian.com/questions/258150 which shows how to set an assignee from ScripteRunner. You will need to change the line

if (user != null)

to match your requirement for a location based entry.

Hope this helps point you in the right direction.
