Sub Report places data on incorrect line of report

rbuser

I have a report that contains a sub-report which calculates employee
renumeration, The problem I am having is that the data from the sub report
actually prints on the line after the line it is supposed to be on. ie the
correct value shows up for the next employee not the one it is supposed to
show for .
Anybody know why this is so. Is it a timing issue?
I have tried all available timings to no avail.

There is not enough information here for me to diagnosed the problem.

1. Make sure that the data is linked correctly. (see article below).

2. Run RBuilder\Demos\EndUser\ReportExplorer and RBuilder\Demos\Reports and
check out the linking examples and the master/detail examples.

3. As a test you can try commenting out the event-handler code associated
with the report. Make sure that you do not have code that manipulates the
dataset in any manner while the report is generating.

4. If you still have an issue, please create a simple example using standard
Delphi components, ReportBuilder and the DBDemos data. Email in zip format
to support@digital-metaphors.com and we can check it out here.

Tech Tip: Linking SQL Queries for Master/Detail Data
------------------------------------------------------

The following example shows two options for linking SQL queries to create a
master/detail relationship.

In this example, we are using Delphi's DBDemos data to create a
Customer/Order relationship. Thus we wish to link the Orders detail to the
Customer master.

I. Delphi Query Linking
------------------------

a. Set the detail TQuery.DataSource property to point to the master
query's TDataSource component.

b. In the SQL "Where" clause for the detail query use a ':' followed by
the linking field name from the master:

example
select *
from orders
where orders.CustNo = :CustNo

Now each time the master record position changes, the detail query will
automatically be refreshed with the correct result set.


II. RB DataPipeline Linking
-----------------------------

a. Set the detail DataPipeline.MasterDataPipeline to point to the master
DataPipeline.

b. Use the detail DataPipeline.MasterFieldLinks property to define the
linking relationship

c. In the SQL for the detail, retrieve all records and sort them by the
linking master field:

select *
from Orders
order by CustNo


Notes:

1. Using RB DataPipeline, each query is executed only a single time - thus
performance is much faster.

2. RB Professional and Enterprise Editions include a visual Data environment
for creating SQL queries, defining linking relationships, and creating
Ask-At-Runtime parameters. Using the RB tools you could create the above
linked queries in about 10 seconds.
