waikeatng: Using RunBaseBatchPrintable class

==============

RunBase framework is used when we develop a class to run an operation within Dynamics AX, such as posting a sales order or used in any data manipulation operation. If we need to batch the operation, we will commonly use the RunBaseBatch framework by extending the RunBaseBatch class.

The RunBaseBatch class does not provide the access to printer such as when running a report. If you need to provide the printer support to allow users to specify the printer options in the operation, you can extend the RunBaseBatchPrintable class instead of RunBasebatch class.

When extending the RunBaseBatch class, you need to override the pack() and unpack() methods. If query is used in the operation, you may need to also override the initParmDefault(), queryRun(), and showQueryValues() methods.

When extending the RunBaseBatchPrintable class, in addition to the above methods, you would also need to make the following amendments:-
1) Modify the pack() to serialise the printJobSettings object (inherits from RunBaseBatchPrintable class)

public container pack()
{
    ;
    return [#CurrentVersion,
            #CurrentList,
            queryRun.pack(),
            printJobSettings.packPrintJobSettings()  // Serialise the printJobSettings object
           ];
}

2) Modify the unpack() to deserialise the printJobSettings object

public boolean unpack(container _packedClass)
{
    Version         version = RunBase::getVersion(_packedClass);
    container       packedQuery;
    container       packedPrintJobSettings;
    ;
    switch (version)
    {
        case #CurrentVersion:
            [version, #CurrentList, packedQuery, packedPrintJobSettings] = _packedClass;
            if (packedQuery)
            {
                queryRun = new QueryRun(packedQuery);
            }
            
            // Deserialise the printJobSettings object
            if (isSwappedFromServer)  
            {
                printJobSettings = SysPrintOptions::newPrintJobSettingsOnServer(packedPrintJobSettings);
            }
            else
            {
                printJobSettings = new PrintJobSettings(packedPrintJobSettings);
            }
            break;

        default:
            return false;
    }
    return true;
}

3) To retrieve the user-selected printer settings, you can use the printJobSettings variable directly in the code. For example:-

public void run()
{
    ;
    info(strfmt('Selected printer is %1', printJobSettings.printerPrinterName()));

    // pass the printJobSettings object to run a report based on the selected printer settings
    reportRun = classFactory.reportRunClass(args);
    reportRun.init();
    reportRun.printJobSettings(printJobSettings.packPrintJobSettings());
    reportRun.run();
}

Happy DAXing!!
