Give your source code.

the code for showing the reports is as follows:
also find attached the two reports and the sq used to create the tables, just delete the .txt extension as I cannot attach the files.

procedure TfReports.ViewReport;
begin
  diaryRpt.LoadFromFile(ExtractFilePath(Application.ExeName)+'/data/readings.lrf');
  diaryRpt.ShowReport;
end;

procedure TfReports.ViewNotes;
begin
  diaryRpt.LoadFromFile(ExtractFilePath(Application.ExeName)+'/data/notes.lrf');
  diaryRpt.ShowReport;
end;

After renamaing the frDBdataSet i had the same experience.
The DataSet of the master-band was not automatically renamed.
