Instead of send message to all users in SM02, you can also send message to a only specific user in SAP by using the transaction code SE37 and function module TH_POPUP.
1. Execute transaction code SE37 and enter TH_POPUP as the function module name. Now, test run on it.
2. Fill in all the details and click on execute. The receiver must be online to receive the message.
Note
• RFC Target System – Standard name of an RFC destination of the receiver system
• CLIENT – Client on which receiver is logged in
• USER – Login ID of receiver
• MESSAGE – Message that you want to send to receiver
• MESSAGE_LEN – Length of the message
• CUT_BLANKS – Fill it with ‘x’
