Yes!
This happens to me too!
I sent a mail to emcollins AT us.ibm DOT com and received an immediate answer:

Hi Karsten,

Thanks for the feedback.

A handfull of people are seeing this bug but so far I have not been able 
to
reproduce it.  I have not seen the -1 return code yet but the few other
folks who see this are all getting the -4 return code and only when the
report or monitor runs as a service although it works interactively as
you've described.

The only work around at this point is to deselect the checkbox for the
custom summary section of your report and/or monitor.   I'm working on
resolving the problem and will let you know when it's resolved.

It would help if you could send me the

TraceReportSvc.txt
LogReportSvc.txt

files from the c:\program files\tivoli\tsm\console_reporting  (or wherever
it's installed).   Information in your trace and log files may provide a
clue especially for the -1 return code.

Thanks!

Been playing with this on a desktop and I get this message on all the
reporting tools if run on the scheduled time. I can right click and select
"refresh using current time" or "refresh using scheduled time" and it will
run. Anyone currently playing around with it seen this?
