Building scalable batch processes with the SysOperation framework in Dynamics 365 F&O

As enterprises scale on Microsoft Dynamics 365 Finance & Operations (D365 F&O), managing high-volume business operations efficiently becomes essential. Processes such as journal postings, payment releases, and large data imports can strain system performance when executed synchronously, resulting in slower response times and reduced user productivity.

To sustain agility and performance at scale, organizations need a structured approach to offload heavy, repetitive, or long-running tasks without disrupting day-to-day operations. Dynamics 365 offers this capability through the SysOperation Framework – a built-in architecture that enables asynchronous, background, and batch processing of complex workloads.

The SysOperation framework in D365 not only enhances system responsiveness but also helps businesses maintain operational continuity, optimize resources, and improve scalability across finance, supply chain, and other core modules.

In this blog, we’ll explore:

• The key components that make up the SysOperation Framework
• A step-by-step process to create a batch job using this model
• Best practices and real-world scenarios where SysOperation drives efficiency and scale

Understanding SysOperation framework for scalable batch processing in D365 F&O

The SysOperation Framework is a Microsoft-recommended pattern for developing batch and service-based operations in D365 F&O. It separates business logic from UI concerns, allowing developers to create clean, modular, and testable batch processes.

Key components

Component	Description
Data contract	Holds input parameters and defines how data moves between the UI and service logic. Marked with [DataContractAttribute] and [DataMemberAttribute].
Service class	Contains the actual business logic and processing code. Extends SysOperationServiceBase.
Controller class	Manages execution and passes the data contract to the service. It also defines whether a job runs synchronously or as a batch. Extends SysOperationServiceController.
UI builder	Customizes the dialog shown to users before execution. Only required when the auto-generated UI isn’t sufficient.
Action menu items	Entry point that executes the controller and allows end-users to trigger the batch job from the navigation pane.

Step-by-step guide: Creating a SysOperation batch job

Let’s create a scalable batch job in the D365 SysOperation framework.

Step 1: Create the data contract class

Define the data contract class to hold the parameters for the batch job.

A batch contract in F&O is defined using Data Contracts, which specify the data structure to be exchanged.

To define the batch contract, follow these steps

1. In Visual Studio, open your Dynamics 365 project.
2. Right-click on your project and select Add > New Item.
3. Choose Dynamics 365 Items > Class and name it SysBatchContract.

Here is a sample X++ code:

[DataContractAttribute]

class  sysBatchContract

{

    str someParameter;

    [DataMemberAttribute]

    public str parmSomeParameter(str _someParameter = someParameter)

    {

        someParameter = _someParameter;

        return someParameter;

    }

}

Step 2: Create the service class

Create a service class that contains the batch-processing logic. This class extends SysOperationServiceBase.

To create service operations:

1. Right-click on your project and select Add > New Item.
2. Choose Dynamics 365 Items > Class and name it sysBatchService.

Here is a sample X++ code: 

class  sysBatchService extends SysOperationServiceBase

{

    LedgerJournalTrans          journalTrans;

    LedgerJournalTable          journalTable;

    PaymentReleaseForm          paymentReleaseForm;

    VendBankAccount             vendBankAccount;

    BankAccountTable            bankAccountTable;

    RecordInsertList            paymentReleaseFormList = new          RecordInsertList(tableNum(PaymentReleaseForm));

    public void processOperation( SysBatchContract _contract)

    {

                try

        {

            ttsBegin;

            this.paymentReleaseInsertion();

            ttsCommit;

     info(“Payment record inserted successfully.”);   

        }

        catch

        {

            ttsAbort;

            info(“An error occurred during process: ” + (CLRInterop::getLastException() ? CLRInterop::getLastException().ToString() : “Unknown error”));

        }

     }

  public void paymentReleaseInsertion()

  {

               //Vendor payments

        while select journalTable

            where journalTable.Posted == NoYes::Yes

            && journalTable.JournalType == LedgerJournalType::Payment

            && journalTable.IsSendForPayment == NoYes::No

            join journalTrans

            where journalTrans.JournalNum == journalTable.JournalNum

        {

            select vendBankAccount

                where vendBankAccount.RecId == journalTrans.VendBankAccount;

            // Create a new record

            paymentReleaseForm.clear();

            paymentReleaseForm.JournalType                  = LedgerJournalType::Payment;

            paymentReleaseForm.RecordType                   = RecordType::P;

            paymentReleaseForm.DebitAccountNo               = journalTrans.BankAccountId;

            paymentReleaseForm.ValueDate                    = journalTrans.TransDate;

            paymentReleaseForm.ProductCode                  = journalTrans.ProductCode;

            paymentReleaseForm.PaymentVoucher               = journalTrans.Voucher;

            paymentReleaseForm.BeneficiaryAccountName       = vendBankAccount.Name;

            paymentReleaseForm.BeneficiaryAccountNo         = vendBankAccount.AccountID;

            paymentReleaseForm.BeneficiaryBankCode          = vendBankAccount.AccountNum;

            paymentReleaseForm.BeneficiaryAddressLine1      = vendBankAccount.addressing();

            paymentReleaseForm.BeneficiaryAddressLine2      = vendBankAccount.addressing();

            paymentReleaseForm.BeneficiaryAddressLine3      = vendBankAccount.addressing();

            paymentReleaseForm.PaymentAmount                = journalTrans.AmountCurDebit;

            paymentReleaseForm.PaymentTransactionCurrency   = journalTrans.CurrencyCode;

            paymentReleaseForm.Invoice                      = journalTrans.MarkedInvoice;

            paymentReleaseForm.IFSC_Sort_NEFTCode           = ‘HDFC0001234’;

            paymentReleaseForm.CustomerTransactionRef_No    = journalTrans.PaymReference;

            paymentReleaseForm.PaymentDetails               = strFmt(“%1 %2”, paymentReleaseForm.Invoice, journalTrans.PurposeCode);   //’Invoice Payment – INV00045′;

            paymentReleaseForm.BeneficiaryEmail_Id          = vendBankAccount.Email;

            paymentReleaseForm.PurposeCode_International    = journalTrans.PurposeCode;

            paymentReleaseForm.PurposeCode_Local            = journalTrans.PurposeCode;

            paymentReleaseForm.Status                       = PaymentReleaseStatus::Pending;

            paymentReleaseForm.ChargeType                   = journalTrans.ChargeType;

            paymentReleaseFormList.add(paymentReleaseForm);

        }

        paymentReleaseFormList.insertDatabase();

        update_recordset journalTable

        setting IsSendForPayment = NoYes::Yes

        join journalTable

        where journalTable.Posted == NoYes::Yes

        && journalTable.JournalType == LedgerJournalType::Payment

        && journalTable.IsSendForPayment == NoYes::No;

     }

}

Summary of what this code does:

• Runs as a batch job via SysOperation Framework.
• Picks posted vendor payment journals that are not yet processed.
• Creates payment release records in a custom table (PaymentReleaseForm).
• Uses bulk insert for efficiency (RecordInsertList → Optimized way to insert multiple records into PaymentReleaseForm in bulk, instead of row-by-row).
• Updates journal records so they won’t be processed again.

Step 3: Create the controller class

The controller class manages the execution of the D365 SysOperation framework default batch job. It should extend to SysOperationServiceController.

To create a batch controller:

1. Right-click on your project and select Add > New Item.
2. Choose Dynamics 365 Items > Class and name it  SysBatchController.

Here is a sample X++ code:

class  SysBatchController extends SysOperationServiceController

{

    protected void new()
    {
            super(classStr(sysBatchService),
            methodStr(sysBatchService, processOperation),
            SysOperationExecutionMode::Synchronous);
    }

    public ClassDescription defaultCaption()
    {
             return “Process Job”;
    }

    public static SysBatchController construct(SysOperationExecutionMode _executionMode = SysOperationExecutionMode::Synchronous)
    {
               SysBatchController controller;
              controller = new SysOperationBatchController();
              controller.parmExecutionMode(_executionMode);
              return controller;
    }

    public static void main(Args _args)
    {
        SysBatchController controller;
        controller = SysBatchController::construct();
        controller.parmArgs(_args);
        controller.startOperation();
    }

}

Step 4: (Optional) Create the UI builder class

If you need to customize the UI dialog, create a UI builder class.

To create batch UIBuilder:

1. Right-click on your project and select Add > New Item.
2. Choose Dynamics 365 Items > Class and name it  SysBatchUIBuilder.

class SysBatchUIBuilder extends SysOperationAutomaticUIBuilder {

    // Custom UI logic goes here

}

Step 5: Add a menu item

Create a new action menu item in the AOT to run the batch job:

1. Object: SysBatchController
2. Object Type: Class

To create an action menu item:

• Right-click on your project and select Add > New Item.
• Choose Dynamics 365 Items > action menu item and name it SysBatchMenuItem.
• Attach the controller class to the menu item property.
• Place it in the desired menu location.

Step 6: Run the batch job

• Navigate to your new item.
• Enter parameters in the dialog.
• Submit the job.
• It runs in the background (if asynchronous).

• Track it in System Administration > Batch Jobs.
