Email triggering for "Created" status

Dear All,

I have implemented service desk. When message is created from satellite system it triggers mail to all super users for that server according to Sold-to part BP maintained in IB52.

But in my scenario 2-3 different locations are using same server. Super users want to get mails only for the issue created from their respective location.

How can I bifurcate mails according to location of end user even though server is same and thus installation no. is also same?

Please help!

Rears,

Nikhil
