Hi:
Is the email attachment a CSV file??? If the CSV file is accessible to SAS on a disk location, then you should be able to read the CSV file with PROC IMPORT or a DATA step program. I am not sure that SAS would be able to "grab" the email attachement while the file was still on a mail server or still attached to a mail message. This would be a question for Tech Support.
To send a question to Tech Support, go to
