Master-detail and SubReports doesn't work
Hi,
I have 3 JITPipelines - one as master and two for details. Master has
field ID (integer) and each detail pipeline has MasterID field.
Pipelines are linked using visual designer.
In report I have some fields from master pipeline and then two
subreports - one for each detail pipeline.
Now the problem is that for some reason one detail subreport prints
whole punch of records for wrong master record (it is 8th master
record but I don't think it is important). I also output the ID and
MasterID fields and they are different, yet subreport prints them...
any idea what is wrong?
BTW It is possible that there is no records for given master in one or
both details.
I'm using D 5.1 Pro and RB 7.03 Pro
TIA

Tech Tip: Use Master/Detail JITPipelines
----------------------------------------------------
To use Master/Detail relationship with the JITPipeline:
1. Check out the demo dm0139 in the main demo reports app
for an example.
2. Make sure you have the Detail JITPipeline.MasterFieldLinks
defined to specify the relationship. In dm0139 the detailed it
linked to the master using the CustNo field from each pipeline.
3. Once you have things setup like the above, then you will need
to connect the Report.DataPipeline property to the master JITPipeline
and the SubReport.DataPipeline property to the detail JITPipeline.
4. In the FormCreate event set each JITPipeline.RecordCount
property to the total number of records for each.
You should not need to reset anything.
6. ReportBuilder expects the data in the detail dataset
to be in sorted order of the field links.
In dm0139, the linked field is the CustNo, therefore
the detail data must be order like this:
CustNo OrderNo
------ -------
1 001
1 002
1 003
2 010
2 009
2 005
