Combine & Merging images to a single image using X++ & C# Dot Net Libraries

How to Merge Two Brands: Successful M&A

Requirement – The requirement is to combine and merging images to a single image using X++ & C# Dot Net Libraries in Microsoft Dynamics 365 finance and operation.

Classes & Libraries –


Sample Code –

str jpg1 = @”c:\images.jpeg”;
str jpg2 = @”c:\images2.jpeg”;
str jpg3 = @”c:\image3.jpg”;

System.Drawing.Image img1 = System.Drawing.Image::FromFile(jpg1);
System.Drawing.Image img2 = System.Drawing.Image::FromFile(jpg2);

int width = img1.Width + img2.Width;
int height = System.Math::Max(img1.Height, img2.Height);

System.Drawing.Bitmap img3 = new System.Drawing.Bitmap(width, height);

System.Drawing.Graphics g = System.Drawing.Graphics::FromImage(img3);

g.DrawImage(img1, new Point(0, 0));
g.DrawImage(img2, new Point(img1.Width, 0));


img3.Save(jpg3, System.Drawing.Imaging.ImageFormat::Jpeg);

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.

Archive inventory transactions (Purge InventTrans) in Microsoft Dynamics 365 for finance and operations

As we know, “InventTrans” table is one of the largest table in Microsoft D365 for finance and operations and this table keep growing through out the ERP lifecycle and consume more space. BUT ! here is the good news that Microsoft has released a standard feature and a standard batch job to archive inventory transactions and purge InventTrans table data.

Here is the Microsoft document link – https://docs.microsoft.com/en-us/dynamics365/supply-chain/inventory/archive-inventory-transactions

D365 FO/AX7: Sharepoint File Upload using X++

Requirement :

Uploading a file in Sharepoint online using X++ and inside from Microsoft Dynamics 365 finance and operations.


The current user id of Microsoft Dynamics 365 Finance and operations should have proper rights and privileged in Sharepoint Online.

Sample Code:

In this scenario i am creating a text file in Microsoft Dynamics 365 finance and operations and then uploading its memory Stream in Sharepoint online using X++ . You can modify the X++ code in D365 finance and operations as per your need.

class RunnableClassRun
/// /// Runs the class with the specified arguments. ///
/// The specified arguments.
public static void main(Args _args)
System.UriBuilder builder = new System.UriBuilder(“https://XXXXXX.sharepoint.com”);
str extId = xUserInfo::getExternalId();
Microsoft.Dynamics.AX.Framework.FileManagement.SharePointDocumentStorageProvider provider;
Microsoft.Dynamics.AX.Framework.FileManagement.DocumentLocation documentLocation = new Microsoft.Dynamics.AX.Framework.FileManagement.DocumentLocation();
provider = new Microsoft.Dynamics.AX.Framework.FileManagement.SharePointDocumentStorageProvider(“XXXXXX.sharepoint.com”, “sites/dummy”, “Shared%20Documents/MyFolder”, extId);
System.Byte[] reportBytes = new System.Byte[0]();
System.Text.ASCIIEncoding enc = new System.Text.ASCIIEncoding();
reportBytes = enc.GetBytes(“YOUR STRING/TEXT”);
System.IO.MemoryStream memoryStream = new System.IO.MemoryStream(reportBytes);
//memoryStream = comma.getStream();
documentLocation = provider.SaveFile(newGuid(), ‘TextFile.txt’, System.Web.MimeMapping::GetMimeMapping(‘TextFile.txt’), memoryStream);



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.
