Tcode: HRPBSINGENCORRLETTER, Mail is going blank.

Hi

I have a requirement from client that when I execute Tcode: HRPBSINGENCORRLETTER it should trigger a mail with some text in the body of the mail, mail is going fine, but it is going blank to the user.

Please help to provide any solution for this so that we can add text in the mail.

Regards

Aparna
