How to send a message to a specific user in sap?

Hi All,
Some-times we need to send a specific message to specific user in SAP which is not possible by using SM02..SO here is the trick to do it :

Use function module TH_POPUP
goto Transaction code SE37 enter the function module name & test run it
the the resulting screen is shown below, type the details and execute.
The user must be logged into the system to receive the message


Enjoy!!
