Develop your own Business Events

Business Events in Dynamics 365 Finance and Supply Chain Management can be used to notify external systems in near-time when a certain event occurs in the ERP system. Dynamics 365 F/SCM comes with a set of predefined business events. You may want to develop you own specific business events to send data to another system. Three artifacts are needed for a custom Business Event. The contract that contains the data that is sent, the Business Event and at least one trigger. Here is an example for a Business Event that triggers when a new customer is created.

Required Model Dependencies:

• Application Foundation
• Application Suite
• Directory
• Contact Person

Contract

[DataContract]
public class ERPCustomerCreatedContract extends BusinessEventsContract
{
    protected Name name;

    [DataMember('Name'),BusinessEventsDataMember("Customer Name")]
    public Name parmName(Name _name = name)
    {
        name = _name;
        return name;
    }

    public static ERPCustomerCreatedContract newFromCustTable(CustTable _custTable)
    {
        ERPCustomerCreatedContract contract = new ERPCustomerCreatedContract();
        contract.parmName(_custTable.name());
        return contract;
    }
}

Business Event

[BusinessEvents(classStr(ERPCustomerCreatedContract),
                'Customer Created',
                'Customer Created',
                ModuleAxapta::Customer)]
public class ERPCustomerCreated extends BusinessEventsBase
{
    CustTable custTable;

    protected void new()
    {
    }

    public static ERPCustomerCreated newFromCustTable(CustTable _custTable)
    {
        ERPCustomerCreated event = new ERPCustomerCreated();
        event.parmCustTable(_custTable);
        return event;
    }

    public CustTable parmCustTable(CustTable _custTable = custTable)
    {
        custTable = _custTable;
        return custTable;
    }

    [Wrappable(false), Replaceable(false)]
    public BusinessEventsContract buildContract()
    {
        return ERPCustomerCreatedContract::newFromCustTable(custTable);
    }
}

Trigger

Make sure the trigger runs after inserted not on inserting 😉

class ERPCustTable_EventHandler
{
    [DataEventHandler(tableStr(CustTable), DataEventType::Inserted)]
    public static void CustTable_onInserted(Common sender, DataEventArgs e)
    {
        CustTable custTable = sender as CustTable;
        ERPCustomerCreated::newFromCustTable(custTable).send();
    }
}

Configuration

Make sure your code builds. In Dynamics 365 F/SCM open the Business Events Catalog. Rebuild the catalog to see your Business Event. Make sure you have an endpoint configured. Activate the Business Event. Create a new Customer. The Business Event will trigger and send the contract to your endpoint.

After creating a new customer, the Business Event triggers and sends the message to the configured endpoint. In my case it’s a Blob Storage in Azure. Here is the resulting JSON Message:

{
"BusinessEventId":"ERPCustomerCreated",
"BusinessEventLegalEntity":"DEMF",
"ContextRecordSubject":"",
"ControlNumber":5637166326,
"EventId":"13258F5D-9734-4EEF-8742-966C903E6896",
"EventTime":"/Date(1700741668000)/",
"EventTimeIso8601":"2023-11-23T12:14:28.5470919Z",
"InitiatingUserAADObjectId":"{2FDBF251-CB38-48ED-87CD-7515B9010431}",
"MajorVersion":0,
"MinorVersion":0,
"Name":"Test Customer",
"ParentContextRecordSubjects":[]
}

Business Events and PowerAutomate (aka. Flow)

I’ve made a video how to use Business Events in combination with Power Automate.
