Are Orders recorded?

http://mydomain.com/OrderReport

gives me

Fatal error: Class 'DataReport' not found in /home/silverstripe/public_html/ecommerce/code/reports/OrderReport.php on line 7

I don't have a Reports Tab, or didn't until

In Ecommerce >Code> Reports > OrderReport.php

It says class OrderReport extends DataReport

I tried changing it to
class OrderReport extends SSReport { .... as a total guess

and yes now Reports now appears at the top ..but doesn't do much no reports show on left

user_error(Please implement getReportField() on OrderReport,256) line 94 of SSReport.php SSReport->getReportField() line 64 of SSReport.php SSReport->getCMSFields() line 172 of ReportAdmin.php ReportAdmin->reportEditFormFor(OrderReport) line 100 of ReportAdmin.php ReportAdmin->show(HTTPRequest) line 159 of Controller.php Controller->handleAction(HTTPRequest) line 129 of RequestHandler.php RequestHandler->handleRequest(HTTPRequest) line 119 of Controller.php Controller->handleRequest(HTTPRequest) line 277 of Director.php Director::handleRequest(HTTPRequest,Session) line 121 of Director.php Director::direct(/admin/reports/show/OrderReport) line 118 of main.php

and thats where the error lies or starts as the is no DataReport

I've hear mention that DataReport isn't used anymore in SilverStripe New versions

Im using silverstripe-v2.3.4 with ecommerce 0.5.3 as its the stable version!

I have a Side reports Tab for quick filtering but it doesn't have anything to do with orders .etc
