If you send a data driven subscription via email there seems to be no chance to influence the name of the attachments.
There is no field to pass the value as when you use a file system subscription (FILENAME).
The sales manager at our client location refuses to open each Excel
spreadsheet attachement in his email to find the sales region and then select
"Save As" with this name for each of their 77 sales regions every month.
Does anybody know a hint how to do this anyway?
