There would be an option in the subscription page to subscribe to "whole" of the report. You got to select that option.
I am not seeing a subscription page. When I receive the email all I have is the attached file no email content.
Is this in the new Insight? There is a limit in place that will only deliver 75 rows in an agent attachment.
Is there a way then to write the report to only show data from the last 30 days? I was looking in the filters but it was not clear.
If you are in the new insight (OBIEE) you can could create SQL expression to limit to 30 days. I put this exxample together the other day. Hope it helps.
