Cognos BI, Use Local Cache odd behavoiur

[TheFaster]

I'm running two nearly identical reports.

Report 1 is an Interactive Report running on CQM.

Report 2 is an Interactive Report running on DQM with Local Cache set to true.

Other than that, the two queries are identical in their models, queries, Native SQL, etc.

However, where the CQM report runs fine and returns the expected data, the DQM report runs and displays a page with only the information headers (Year, Total, etc.)

Any idea what could be causing this?
