Display Data from 1 Table with Subdetails

edited July 2019 in FastReport VCL 5
Hello,

I want to print the history of a batch number on a fast report.
Therefore I have a database table which contains all dependent batch numbers in one table.

To identify the dependencies between the batchnumbers I have a column called "Level" and a column called "NextID" and "PreviousID".
Now I want to create a report which displays the dependencies and the levels in a Drill-Down or in a tree view.

Example of my table is attached!



Thanks for any hints.
