This is the merging behavior of the dataviews. They should merge the
dataviews into the main report when you load a template.
What you can do is delete the dataviews from the templates that you are
going to load as subreports. … -
Yes, there was a problem simliar to this. We can email you a patched unit
for 6.03 which addresses this issue. Send an email to

We have released RB 7 for Delphi 5, 6 and 7, which is now the latest
version. You'll have to upgrade to RB 7 in order to use these properties
with the technique Tom spoke of. Contact info@digital-metaphors.com with

RB 4? Yikes. Then my suggestion ain't so great. You need RB 6.03 to use

…Is the main report connected to a data pipeline? The subreport should only

Digital MetaphorsThe crosstab should be next to the subreport in the detail band. Imagine
that the crosstab is like the subreport in that it will traverse and print N
detail records. If you place the crosstab in the same detail band as the

Can you send us your simple project? Since you are using JITs then you can
contrive a few records for us and we should be able to reproduce the error
this way. Send it to support@digital-metaphors.com

It is not a good idea to place section subreports in a band with other

Sorry, I misunderstood. You can't sum using DBCalcs in the main report over
