D365 FO : Developing Business Events with X++ from scratch

Microsoft Dynamics AX/D365 F&O Technical blog

Business events provide a mechanism that allow external system receives notifications from Microsoft Dynamics 365 Finance and operations. For example – When you are posting a purchase invoice then you can send notifications/ payload / message to an external system.

You can use existing standard business events which are available in the D365 FO or you can also develop and customize new business events as per your need.

There are 2 ways you can consume business events . 1. Power automate (Microsoft Flow) 2. Azure messaging services.

Scenario – In this example, I am going to show you how we can develop a new custom business event from scratch. In my scenario, business event in D365 FO should be triggered when a user is posting purchase invoice in Microsoft dynamics 365 for finance and operations.

There a 2 standard and base classes which i will use to develop custom business events –

  1. BusinessEventsContract ( Use for developing/defining payload message)
  2. BusinessEventsBase ( Use for triggering custom business event)

Create a PAAPurchInvoiceJournalPostBusinessEventContract class

class PAAPurchInvoiceJournalPostBusinessEventContract extends BusinessEventsContract
private VendAccount vendAccount;
private PurchId purchid;
private InvoiceId invoiceId;

private void initialize(VendInvoiceJour _vendInvoiceJour)
vendAccount = _vendInvoiceJour.OrderAccount;
purchid = _vendInvoiceJour.PurchId;
invoiceId = _vendInvoiceJour.InvoiceId;

public static PAAPurchInvoiceJournalPostBusinessEventContract newFromVendInvoiceJour(VendInvoiceJour _vendInvoiceJour)
PAAPurchInvoiceJournalPostBusinessEventContract contract = new PAAPurchInvoiceJournalPostBusinessEventContract();
return contract;

private void new()

[DataMember(‘VendAccount’), BusinessEventsDataMember(‘VendAccount’)]
public vendAccount parmvendAccount(vendAccount _vendAccount = vendAccount)
vendAccount = _vendAccount;
return vendAccount;

[DataMember(‘PurchId’), BusinessEventsDataMember(“PurchId”)]
public PurchId parmPurchId(PurchId _purchId = purchId)
purchId = _purchId;
return purchId;

[DataMember(‘InvoiceId’), BusinessEventsDataMember(“InvoiceId”)]
public InvoiceId parmInvoiceId(InvoiceId _invoiceId = invoiceId)
invoiceId = _invoiceId;
return invoiceId;


Create a PAAPurchInvoiceJournalPostBusinessEvent class

“Custom Vendor Invoice Post Business Event”,
“This business event is triggering during the time purchase invoice posting”,ModuleAxapta::AccountsPayable)]
class PAAPurchInvoiceJournalPostBusinessEvent extends BusinessEventsBase
private VendInvoiceJour vendInvoiceJour;

static public PAAPurchInvoiceJournalPostBusinessEvent newFromVendInvoiceJour(VendInvoiceJour _vendInvoiceJour)
PAAPurchInvoiceJournalPostBusinessEvent businessEvent = new PAAPurchInvoiceJournalPostBusinessEvent();

return businessEvent;

private VendInvoiceJour parmVendInvoiceJour(VendInvoiceJour _vendInvoiceJour = vendInvoiceJour)
vendInvoiceJour = _vendInvoiceJour;
return vendInvoiceJour;

private void new()

[Wrappable(true), Replaceable(true)]
public BusinessEventsContract buildContract()
return PAAPurchInvoiceJournalPostBusinessEventContract::newFromVendInvoiceJour(vendInvoiceJour);


you must add below block of code in purchase invoice posting routine class. Also business must be activated or enabled in that company. Business event will trigger when purchase invoice posting will take place.

VendInvoiceJour vendInvoiceJour = this; // vendInvoiceJour buffer

PAAPurchInvoiceJournalPostBusinessEvent::newFromVendInvoiceJour(this).send () ;


Build your project solution and navigate to path -[System administration–> Setup –> Business Events –> Business Events Catalog] to see and activate your business event.

D365 FO – Create deep links, shareable, secured URLs in Microsoft Dynamics 365 for finance & operations

A complete guide to mobile app deep linking | Adjust

What is deep links in Microsoft Dynamics 365 for finance and operation? Deep links are shareable and secures URLs to a specific form. Optional filters can be passed so that when user will open the deep link and navigate to a specific form then it will show filtered data ore records. In Microsoft D365 FO, below library – Microsoft.Dynamics.AX.Framework.Utilities.UrlHelper.UrlGenerator is used to generate deep links using X++ .

Sample Code – Below is the sample code of developing & generating deep links for D365 FO forms and records using filter and ranges in form data source. In below example, i am generating the sharable URL (deep link ) of a form – CustAccount and applying a “CustAccount” filter on custTable datasource.

using Microsoft.Dynamics.AX.Framework.Utilities; // setting library/Dll reference

class DeepLinkTest
    public static void main(Args _args)
        MenuItemNameDisplay menuItemName                = menuItemDisplayStr(CustTable);  // customer form
        MenuItemType        menuItemtype                = MenuItemType::Display;
        str                 filterformDataSource        = formDataSourceStr(CustTable, CustTable);  // filer datasource
        str                 filterFormDataSourceField   = fieldStr(CustTable, AccountNum); // filter field

        UrlHelper.UrlGenerator generator = new UrlHelper.UrlGenerator();
        System.Uri currentHost = new System.Uri(UrlUtility::getUrl());
        generator.HostUrl = currentHost.GetLeftPart(System.UriPartial::Authority);
        generator.Company = curExt();
        generator.MenuItemName = menuItemName;
        generator.MenuItemType = menuItemtype;
        generator.Partition = getCurrentPartition();
        generator.EncryptRequestQuery = true; 
            UrlHelper.RequestQueryParameterCollection requestQueryParameterCollection;
            requestQueryParameterCollection = generator.RequestQueryParameterCollection;
            requestQueryParameterCollection.UpdateOrAddEntry(filterformDataSource, filterFormDataSourceField, "CustAccount"); // applying filter

        System.Uri fullURI = generator.GenerateFullUrl();
        Info(fullURI.AbsoluteUri); // getting deep link


D365 FO/AX7/Class Extension: COC (Chain of command) & Method Wrapping With Example

  • Introduction COC (chain of command) & Method Wrapping In Microsoft Dynamics 365 finance and operations –
  • Microsoft D365 Finance and operations supports very powerful feature called COC or method wrapping.
  • In past, Microsoft Dynamics AX/Axapta supports overlayering where you can overlayer Microsoft classes, table methods etc directly by placing your code in the middle, bottom or top if standard code. Below is screenshot and example for your reference. In below screenshot i placed my custom code in the middle of standard method by using overlayering.
  • In Microsoft Dynamics 365 finance and operations (After version 8.0) , you cannot overlayer code as everything is sealed now. We have to use COC or method wrapping.Microsoft has improved the Functionality of Class extension for D365 FO by adding wrap logic around methods which are defined in the base class that you are augmenting. You can Wrap or do Chain of command (COC) of public and protected methods.
  • In below screenshot i am using method wrapping or class extension of standard class which is different from Microsoft Dynamics AX overlayering approach.

  • Next keyword means to call the orginal method “ChecItemPostingDate” of standard class “InventUpdate”
  • You can get values of Global Variables of in your extension class of your parent class or main class.
  • Final Modifier means The method can’t be overridden in any class that derives from its class.
  • Here are one more example where we are using COC (chain of commands) in Table methods.

Benefits Of Using Change Of Commands instead of Old Overlayering approach in Microsoft Dynamics 365 finance and operations

  1. Easy Future upgrades and version enhancements as you are not doing overlayering in standard classes or methods or objects & keeping you separate extension classes.
  2. Neat & Clean development as no need to compile whole code librarary.

D365 FO/AX7: Composite Data Entities Vs Data Entities With Example

  • Introduction – Data management framework of Microsoft Dynamics 365 finance and operations contains a very important technical asset called Data Entities. Data entities are conceptual combinations, abstraction and encapsulation of one of more underlying tables. Data entities in Microsoft D365 finance and operations are used to import and export data in Microsoft Dynamics finance and operations. Odata integration can also be achieved using D365 finance and operations data entities. We can customize standard data entity . Click Here to know about standard data entity customization.
  • Composite Data entity vs Simple Data Entity- There are some differences between Composite Data entity & Simple Data Entity. 1 ) First of all simple data entity contains one or more tables where as composite data entity contains multiple data entities 2) Simple Data entities support Odata & can be used in Odata integration whereas Composite data entities cannot be used Odata integration.
  • Where should we use Composite Data entity ?-Composite entity is used in scenarios where an entity can be represented as a single document, like Purchase Header/line , Sales header/line, Invoice header/line etc.
  • Example & Development of Composite Data entity steps are mentioned below :
  • In example i am taking 2 separate standard data entities i.e. PurchPurchaseOrderHeaderV2Entity & PurchPurchaseOrderLineV2Entity
  • PurchPurchaseOrderHeaderV2Entity contains purchase order header information & fields mainly purchTable Fields
  • PurchPurchaseOrderLineV2Entity contains purchase order Lines information & fields mainly PurchLine Fields
  • We will develop a new composite data entity by using above 2 data entities and compose data entity will represent a single purchase order document (Purchase Order Header + Purchase Order Line)
  • Now create a composite data entity in your project.
  • Extend PurchPurchaseOrderLineV2Entity and create relation with PurchPurchaseOrderHeaderV2Entity. (NOTE In my case standard relation is already there so no need to create any customize relation)
  • Right click on your composite data entity and add “New Root Data Entity Reference” and make sure property Data Entity should be equal to PurchPurchaseOrderHeaderV2Entity
  • Right click on your “New Root Data Entity Reference” PurchPurchaseOrderHeaderV2Entity and add “New Embedded Data Entity Reference” equals to PurchPurchaseOrderLineV2Entity & Property Relation should be equal to PurchaseOrderHeader.
  • Extend staging table (PurchPurchaseOrderLineV2Staging) of data entity PurchPurchaseOrderLineV2Entity and add relation with the staging table (PurchPurchaseOrderHeaderV2Staging) of data entity PurchPurchaseOrderHeaderV2Entity.(NOTE : In my case standard relation already exist so i am not creating any relation)
  • Add two columns, RowId and ParentRowId (type int), on all the staging tables i.e. PurchPurchaseOrderHeaderV2Staging & PurchPurchaseOrderLineV2Staging.
  • Create a cluster index on the staging tables which includes RowId, ParentRowid,DefinitionGroup, and ExecutionId for getting good performance .
  • Build and synchronize your project
  • Under “Data import/export framework parameters”, select fast tab “Entity Settings” and click on “Refresh Entity List”. Here is LINK AND TUTORIAL.

D365 FO/AX7: Multithreading With Example Using Pessimistic LOCK & BatchHeader/BatchTask Class

Background – In Microsoft Dynamics D365 Finance and Operations, most of the processes & batch jobs run in a single thread and supports only single thread execution not multi-threading. Generally Single Thread batch Jobs or processes work well in Microsoft Dynamics 365 Fins and ops. But there are many scenarios where we require fast performance and quick competition of processes and batch jobs. Multithreading Batch Jobs approach is very useful in those scenarios.

Two Different Ways In Microsoft Dynamics D365 Finance and Operations,We can develop Multithreaded Batch Jobs in two ways. The first approach is using PESSIMISTIC LOCKS OR PESSIMISTIC SELECT in Microsoft Dynamics D365 Finance and Operations.

The second is to create BATCH TASKs. Batch Task approach you can find in standard classes like RetailStatementCalculate_Multi, RetailStatementPost_Multi Etc. which are using RunBaseBatch Framework (Not SYSOperation Framework) inside Microsoft Dynamics D365 Finance and Operations.

Lets begin with first approach i.e. using PESSIMISTIC LOCKS OR PESSIMISTIC SELECT in Microsoft Dynamics D365 Finance and Operations.By default, D365 fins and ops supports Optimistic Concurrency model (OCC) during the time SELECT or fetching records from database of Microsoft Dynamics D365 Finance and Operations. Optimistic Concurrency Model or SELECT only locks records during the time of Update whereas Pessimistic Concurrency Control (PCC).

Below code you can utilize in batch jobs and you run multiple thread of same batch job class as we a

Lets move to second approach , which include create and adding RUNTIME task using BATCHHEADER class . Here a single Runbase Batch Job is used for creating multiple threads or Runtime Tasks.

D365/AX7: Edit Method In Table Extension Of Standard or Base Table or Custom Table

In past, i explained D365/AX7:Display Method In Table Extension Of Standard or Base Table. Display method value cannot be edited but in Edit Method users can edit the value.

Sample Code

Add the below method in extension class of table and use the same in Form Control .

edit int largeDescriptionEdit(boolean _set, Description _largeDescription)
	AcxBankAccountTable acxBankAccountTable;
	int  ret;

	acxBankAccountTable = AcxBankAccountTable::find(this.Name, _set);

	if (_set)

		acxBankAccountTable.LargeDescription = _largeDescription;

		ret = acxBankAccountTable.LargeDescription;

	return ret;

D365/AX7: Uninstall/Remove a Model/Package From Production & UAT Environment


Uninstall/Remove a Model/Package From Production & UAT Environment of Microsoft Dynamics Finance and operations.


  1. Create a file that is named ModuleToRemove.txt.
  2. In the file, put the name of each module that you want to remove on a separate line. Make sure that you’ve completed the prerequisites for each module that you’re removing.
  3. Create a valid deployable package, and put the ModuleToRemove.txt file in the package\AOSService\Scripts folder.
  4. Install/Deploy the deployable package in UAT or production environment.
  5. Verify that the package was uninstalled before you complete this procedure in a production environment.
