Problem with Master Detail

rbuser

Hello, I have a problem with master detail... I have a Mster with 250
records... but I use mailing label, with 6 mailing labels to paper... and, I
have to all most 45 pages... each master I have a detail, n-n, my detail I
using Sub-Report....

but my report only show me 15 pages... why these? What I forgot ?


thanks for all...

Hi Fillipe,

ReportBuilder simply prints the data you give it. Are there any cases where
there is no detail data for a master field? If so, be sure the
SkipWhenNoRecords property is set to False for the detail pipeline. Also,
take a look a the following article for more information about Master-Detail
reports.

------------------------------------------------
TECH TIP: Fundamentals of Report Data Traversal
------------------------------------------------


1. Single Table Listing Report

Assign the Report.DataPipeline property and leave the
DetailBand.Pipeline unassigned.

The report will traverse the data from start to end (based on the
datapipeline range settings and honoring any filters you've placed on
the datset etc.)


2. Master/Detail Report:

A. Assign the Report.DataPipeline property to the master. Create a
subreport in the detail band and assign the childreport.DataPipeline to
the detail datapipeline.

Use either the visual linking features available from the Report
Designer's Data tab, or Use standard Delphi dataset linking to define
the relationships between the datasets.

The Report will traverse the master records and for each, the subreport
will traverse the detail data related to the master.


3. Master with 2 Details

Configure as in 2 above. Add an additional subreport to the detailband.
Set subreport.ShiftRelativeTo property to the point to the first
subreport. Connect the ChildReport's DataPipeline to the detail data.


4. Report connected to no datapipelines.

When Report.AutoStop is set to True, the Report will print a single
detail band.

When Report.AutoStop is set to False, the Report will print detail bands
until instructed
to stop. You can control when the report stops by setting the
Report.PageLimit property or by calling Report.DataTraversalCompleted
method. Otherwise the report will never stop.


Additional Notes:
----------------

1. SubReports have a Report property that is of type TppChildReport.
Thus, programmatically you can code SubReport.Report.DataPipeline :=
myDataPipeline.

2. ChildReport's traverse data following the same rules as above. A
ChildReport prints in its entirety each time it gets a turn to print.

3. For a Child style SubReport use the Title/Summary band rather than
the Header/Footer (or use a GroupHeader/GroupFooter combo). A standard
Header/Footer will not work because these always print at the very
top/bottom of the page.

4. Do not filter the dataset of modify it any way once the report.Print
command is issued. If you need to do master/detail and cannot use
linked datasets, then use the master DataPipeline.OnRecordPositionChange
event to filter the detail dataset.

5. The reports and datapipelines use dataset bookmarking. Make sure
the dataset can support bi-directional navigation.



Check out the RBuilder\Demos\Reports\Demo.dpr project. Reports 0071,
0072, 0073 show examples of master w/mutliple detail style reports.
Number 0072 has two detail reports.
