Converting Reports RB 5.0 (Delphi 5) -> RB 11.05 (Delphi 7)

rbuser

Hi,

What's the best way to migrate my reports done in ReportBuilder 5.0 (Delphi
5), that has the templates stored in database, to ReportBuilder 11.05
(Delphi 7)? After I use the method loadfromdatabase and click on button
printpreview some master/detail reports aren't ok. Thanks.

Perhaps this applies to your situation….

Article: Migrating Master/Detail reports from RB 5
--------------------------------------------------------------------

Starting with RB 5.5, the data traversal logic and report engine have been
enhanced to support the new DADE linking features and to improve the ability
of subreports to handle detail data.

In the past the subreport did NOT properly honor the detail datapipeline
SkipWhenNoRecords property. Now that this deficiency has been fixed it is
causing some confusion.


To convert old reports that use subreports to print detail data:

1. Set the detail DataPipeline.SkipWhenNoRecords property to False.

When SkipWhenNoRecords is False, master records that contain no detail data
will NOT be skipped and will appear in the report.

2. Use the default NoDataBehaviors property value of [ndBlankPage].

When ChildReport.NoDataBehaviors = [ndBlankPage], the subreport will simply
exit and not print if there is no detail data.

Note: The NoDataBehaviors property was added in RB 5.52 to provide better
control over how a report/subreport behaves when there is no data.
