I am not an admin and I do not play one on TV....
My users asked if the default option when setting email options be changed to "Attach the report" rather than "Include a link to the report" when scheduling. Oddly, I find the default already is "Attach the report" for every other place you can edit email options *except* via scheduling. If you run with options from Cognos Connection or select email from Cognos Viewer it always comes up with attach the report as the default. I can't imagine why it would be different in scheduling, but it sure is in our installation (10.1).
I don't see anything in the documentation that covers altering this default, only that you can hide the "Attach the report" option entirely.
Any thoughts on what this would take to do?
The email options are generated from the following xts:
..\c10\templates\ps\portal\emailOptions\email_options.xts
In 10.2, the part that needs to be modified is at row 2123. Just do a search for m_ro_emailAsURL.
The logic to decide whether to check the attach or link is a bit wonky, but it should be easy enough to simply override it to always have m_ro_emailAsAttachment checked. Just remember to back it up and restart the service.
