Hi all
I am using oracle app 11.5.10.2.
Is it possible to send notification to a particular user through email when a new customer is created in the system (automatically by giving some email_id)?

Thanks in advance.

You should be able to use Oracle Alert to do this, the user guide is available here http://download.oracle.com/docs/cd/B25284_01/current/acrobat/115alrug.pdf

If you don’t want to use Alert, then you can create a WF/or package and can subscribe to standard Business Event which is invoked by standard oracle when creating a USER.
Business event name is oracle.apps.ar.hz.User.create. so create a WF which receives this event and send notification to users /(based on profile).will do this. Or can use a database package as subscription and can send via smtp utility.
