Of all the issues that can come up from this error message, I have not found this one anywhere. It’s a combination of running the FRx launcher (not designer) and a report with rounding. The top is the error message and the bottom is what the launcher should be displaying.
I tried this on two different FRx service packs (sp11 and sp12) and different computers with the same results. The work-around is to do one of the following:
1. Remove rounding on the row.
2. Create another catalog ID with no rounding.
3. Ignore the warning – the report viewer will launch after the report is done.
