Slow performance using Master-Detail with ODBC
We moved from XML data to ODBC databases to speed up performance.
The reports we use always contains a Master table with one or more Detail tables.
The problem seems to be that all the Details rows are retrieved and filtered by the report on the relatation at the end.
We found this thread at the forum, that seems to describe the same problem, however without a solution:
[topic="6795"]Master Detail Slow Preview, Master Detail Slow Preview after loading data form DB[/topic]
Is there a solution for this already?
We use version 1.6.64 at this moment.

You may speed up the report by setting the master data band's PrintIfDetailEmpty property to true.
Yes, this is how the master-detail report is working. All detail rows are fetched and filtered using the master-detail relation.
