Report shows data in HTML view, PDF and other blank

[ohiocort]

This is driving me batty.

I have a report in Cognos 10 Report Studio that runs on a schedule every morning and sends a pdf to users. Works great.

I needed to copy this report and make a change to run once for a one-off request. When I run in HTML, I see the data but as soon as I try to email it in any format, the result is always "No Available Data".

Is this a cache issue? The only change I made was adding a filter for specific dates (every Sunday in January) so several OR lines.

Any ideas? Thanks! - Cort
