Records disappear in Master/Detail report

rbuser

I am using Delphi 7 with RB 7.03. I have a Master/Detail relationship using
Advantage Database Tables.

The report was functioning fine previously, but as I added more data, then
the report started behaving weirdly. If you set the report to OnePass then
it shows all detail records, but when you print then it removes all but 2 of
the detail records. If I set it to TwoPass then it also runs through the
report until it gets to the end, and then it removes all but 2 of the
records. So in the beginning you can see the records, but then they just
disappear.

Any ideas why? What happens at the end that could cause this?

Thanks,

Douglas

I sent a sample project to the support email. Just so you know, it does
this in the preview window of the editor, so it has nothing to do with any
of my code. My sample that I sent has no extra code and it still does it.

Hi Douglas,

I'm sorry but we did not receive your email. If you would like to send it
again, I would be more than happy to take a look at it for you.
(support@digital-metaphors.com) The most common reason for this type of
behavior is that the report engine is becoming lost due to some data
processing or event handler code being executed during report generation.
As a quick test, try disconnecting all your event handlers and try the
report again. If this cures the problem, periodically begin adding your
events back into your code to perhaps isolate the problem.

Like you will see in my sample, no event handlers are in the sample and it
still does it. I resent the sample application just barely, hopefully you
get it this time, under a different email address.

For anyone else reading this thread, the issue was related to master/detail
data configuration.

ReportBuilder supports two different types of data linking: Delphi TDataSet
linking and RB DataPipeline linking. These type of linking are mutually
exclusive - use one or the other, but not both.
