Then master-detail is very simple to implement - it is exactly like the VCL TTable - read the Delphi help for more detailed instructions. Don't expect wonderful performance using tables, though.

The important things to do are:

1. Make sure you have correct KeyLinks for both the master and the detail sets.
2. Set the MasterSource property of the detail set to the TDatasource you have connected to the master set.
3. Set the MasterFields property to the column (or columns) that forms the links, having the detail's column on the left, e.g. IDDEPAR=ID

That should do it.
