extension of SalesHeadingController class

Hi Everyone,

I have added some fields for the SalesHeading Report and also written extension code for the salesHeadingController. the code shown below.

class SalesHeadingControllerExt extends SalesHeadingController
{
public static SalesHeadingControllerExt construct()
{
return new SalesHeadingControllerExt();
}

public static void main(Args _args)
{

SalesHeadingControllerExt controller = SalesHeadingControllerExt::construct();
controller.init(_args);
controller.parmReportName(ssrsReportStr(NS_SalesHeading, Report));
controller.startOperation();
}

}

the code build successfully but when I debug the code its not triggering. I'm trying to customise the following report.

I guess, when we select the sales order per customer(Menu Item), salesheading report will execute.

Please help me with the right approach.

Many thanks

Sheshu Nara

RE: extension of SalesHeadingController class

If I was you, I would debug the code to see where the value changes.

By the way, I looked into SalesHeadingController class and noticed that it has init() method, where the standard code sets the report name. It runs before initializeParameters(), therefore it shouldn't be the cause of this problem, but it would make logical sense to put our logic at the same place.

Thanks Martin, code was build successfully and when I debug the code it's triggering but not executing the customised report, its still executing the standard report.

RE: extension of SalesHeadingController class

Oh, sorry, this is indeed a bug.

super() is used with inheritance, while we need 'next' in extensions:

protected void initializeParameters(boolean _calledFromInitParmDefault) { this.parmReportName(ssrsReportStr(XyzSalesHeading, Report)); next initializeParameters(_calledFromInitParmDefault); }

Where did you find outputReport() method. I see it neither in SalesHeadingController not its parent classes, therefore it indeed doesn't seem to exist.

What if you try initializeParameters() instead?

protected void initializeParameters(boolean _calledFromInitParmDefault) { this.parmReportName(ssrsReportStr(XyzSalesHeading, Report)); super(_calledFromInitParmDefault); }

Hi Martin, I have got the following error. could you please help with this.

in the standard controller class there is no outpurreport method, maybe the reason its showing the error.

RE: extension of SalesHeadingController class

What you wrote isn't an extension of SalesHeadingController class. Instead, you've created a new class inheriting from SalesHeadingController.

Unless you write some other code using this class, the class isn't used and therefore it has no effect whatsoever.

An extension would be defined it this way:

[ExtensionOf(classStr(SalesHeadingController))] final class MySalesHeadingController_Extension { }

You can find more information in F&O documentation: Class extension - Method wrapping and Chain of Command.
