Here is the piece of code you can use to send email with attachments in SQR.

BEGIN-PROCEDURE sendmail
let $subject = 'Subject of the Email Here'
let $to_list = 'email@email.com'
let $ReportID = 'G:\PeopleSoft\Reports\Report_Name.pdf'
let $alias ='Attachment File Name Alias including the file extension'
let $enter = chr(10)chr(13)
let $body_txt = 'Hi,'$enter$enter'Please Find the Report attached with this email.'$enter$enter'Regards,'$enter 'Peoplesoft Application Support'$enter$enter'PS: We request you not to reply to this automated mail trigger.' let $mail-cmd = 'F:\PSFT819\bin\server\winx86\psmail -TO"'$to_list'" -SUBJECT"'$subject'" -BODY"'$body_txt'" -FILE"' $ReportID '" -ALIAS"'$alias'"'
CALL SYSTEM USING $mail-cmd #Status
end-procedure

You would have to change the value of the variable $mail-cmd based on th path of your PS_HOME.
