Batch Job Multi threading D365FO AX7

Multi-threaded batch job

Normally, when we schedule our "Run Base Batch" class as a batch job, it will create a single task. Which will be responsible to execute the complete process in a single thread.

But, As you know like AX-2009 and AX-2012. In D365FO We can add multiple AOS servers in a single batch group and they can process multiple tasks simultaneously. 

In this demo, I will show, How to create a multi-threading Batch job.
following are the steps
Step-1 Create a table for demo purposes in our demo we keep the table name is SLD_DemoTable.

Step-2 Create a class with the name SLD_DemoBusinessLogic and write your business logic in this class.
In the demo, I write only to insert records in a table and show you guys how it works.

Reference Code

class SLD_DemoBusinessLogic

{

    public void processInit(VendTable _vend)

    {

        SLD_DemoTable   SLDDemoTable;

        SLDDemoTable.clear();

        SLDDemoTable.VendName=_vend.name();

        SLDDemoTable.VendAccount=_vend.AccountNum;

        SLDDemoTable.insert();

    }

}

Step-3 Create a batch job class with the name SLD_DemoMultiThreadTask.
This class we will use as Task in the main batch job.

Step-4 In this class We Create a getter setter to store vend table buffer;
Step-5 Create an object of our business logic class and execute the method

Reference Code

public class SLD_DemoMultiThreadTask extends RunBaseBatch

{

  

  VendTable ventTableBuffer;

    #DEFINE.CurrentVersion(1)

    #LOCALMACRO.CurrentList

        ventTableBuffer

    #ENDMACRO

        public ClassDescription caption()

       

        {

              ClassDescription ret;

          

              ret = 'Update Multiple Thread task';

          

              return ret;

          

        }

    container pack()

    {

        return [#CurrentVersion,#CurrentList];

    }

    public boolean unpack(container _packedClass)

    {

        int version = conPeek(_packedClass,1);

   

        switch (version)

        {

            case #CurrentVersion:

                [version,#CurrentList] = _packedClass;

                break;

            default:

                return false;

        }

        return true;

    }

    public void pramVendBuffer(VendTable _vend)

    {

        ventTableBuffer=_vend;

    }

    public void run()

    {

        try

        {

            SLD_DemoBusinessLogic       SLDDemoBusinessLogic=new SLD_DemoBusinessLogic();

            SLDDemoBusinessLogic.processInit(ventTableBuffer);

     

        }

        catch

        {

            info(strFmt("%1",xSession::xppCallStack()));

        }

    }

}

Step-6 Now Create the main batch job which will respond to create multiple tasks in the single batch job.

Reference Code

class SLD_DemoMultiThreadBatch extends RunBaseBatch

{

    BatchHeader                             batchHeader;

    VendTable        vendTable;

 

    public static void main(Args args)

    {

        SLD_DemoMultiThreadBatch  objMultiThread = new SLD_DemoMultiThreadBatch();

        if (objMultiThread.prompt())

        {

            objMultiThread.run();

        }

    }

    void run()

    {

        SLD_DemoMultiThreadTask                 SLDDemoMultiThreadTask;

       

        try

        {

          

            while select firstonly10 vendTable

            {

                if(this.isInBatch())

                {

                    if(!batchHeader)

                    {

                        batchHeader = BatchHeader::construct(this.parmCurrentBatch().BatchJobId);

                    }

                    batchHeader.parmCaption("Multiple thread batch jobs");

                    SLDDemoMultiThreadTask =  new SLD_DemoMultiThreadTask();

                    SLDDemoMultiThreadTask.pramVendBuffer(vendTable.data());

                    // add tasks to the batch header

                    batchHeader.addRuntimeTask(SLDDemoMultiThreadTask, this.parmCurrentBatch().RecId);

                }

                else

                {

                    // execute your code here when not running in batch

                }

            }

            if(batchHeader)

            {

                // save the batchheader with added tasks

                batchHeader.save();

            }

        }

        catch

        {

            info(strFmt("%1",xSession::xppCallStack()));

        }

    }

    public container pack()

    {

        return conNull();

    }

    public boolean unpack(container packedClass)

    {

        return true;

    }

}

Step-7 Now create an Action menu item and reference our batch job SLD_DemoMultiThreadBatch .

Step-8 Build and sync database and module and run the job.
Step-9 Navigate to your batch job page and find your job and check Job Task.

Step-10  before execution of the batch job check the demo table. 
you can check the below screenshot currently table is empty.

After execution of the job table filled with vendors' names.
