Hi everyone, I am working with jasperserver 3.5 and I am using scheduled reports. I set it to send me emails weekly. Everything is ok but I have to questions: 1- Is it possible to set dates or a string dynamically in the subject of emails? For example, I want it to show dates on the subject section of the email. 2- Is it possible to set that if the email is empty it avoids sending mails? I need the answers soon, thanks
