didn't you read the thread?
I haven't solved it by using SEND MAIL (which is the point of this thread), but instead I created a workaround by using ACTIVITY to do the sending of email. In which I made use of CL_BCS class to control which texts should be bold.
Now do you want me to discuss how to use ACTIVITY? How to use CL_BCS class in the code? Seriously?
Lazy people sometimes don't see the answer right in front of their noses because they want easy and fast access to everything.
