Add a calculated field to an AIF Document

AIF is great for application integration and providing external applications required data. Document exports can be generated very easily by providing a query to the AIF document wizard. However, if you want to provide not only table fields but calculated values (e.g. display methods) in an AIF document some work is required. This is an example how to add the CustInvoiceJour.contributionMargin() method to the SalesSalesInvoiceService.

Parameter methods

Add the following methods to the AxCustInvoiceJour class. (You may duplicate the parm* and set* method from an existing field e.g. InvoiceAmount and change the name and parameter.)

public AmountMst parmContributionMargin(AmountMst _margin = 0)
return custInvoiceJour.contributionMargin();

protected void setContributionMargin()

Add a macro in the class declaration of the SaleSalesInvoice_CustInvoiceJour class

class SalesSalesInvoice_CustInvoiceJour extends AfStronglyTypedDataContainer
// lot more here ..



Add the following methods to the SaleSalesInvoice_CustInvoiceJour class

public boolean existsContributionMargin()
return this.exists(#ContributionMargin);

public AmountMST parmContributionMargin(AmountMST_value = 0)
return this.get_Attribute(#ContributionMargin);

Refresh the schema definitions

Open the AIFDocumentSchemaTable in the table browser and delete the record for the DocumentName SalesInvoice.

Delete the SalesInvoice record from the AIFDocumentSchemaTable

In the AOT navigate to the SalesSalesInvoiceService. From the context menu choose to register the service. This will populate the AIFDocumentSchemaTable with the new XML schema including the new field.

Don’t’ forget to activate the new field in your endpoint. Navigate to Basic > Setup > Application Integration Framework > Endpoints > Action Policies > Data Policies > Data Policies and active the new field.

Activate the new field in the AIF data policies

Now you’re ready to test your work. In this example navigate to Accounts Receivable > Inquiries > Journals > Invoice and click on send electronically. Depending on your AIF configuration, check the output. Your new field should be there. Here is the XML from AIF Queue Manager processing an AIF message to a File System Adapter:

Dynamics AX 2009: FTP Adapter for AIF

The Application Integration Framework in Dynamics AX is an extensible framework for data transportation and reception. It support the separation of transport technology (e.g. MSMQ, XML/SOAP Webservices, Filesystem Share) security aspects (services, permissions, transported data) and data manipulation. Creating new adapters to support other transport technologies is simple. Here is an example to support FTP.

Develop AIF FTP Adapter

  • First, create a new parameter table AifFTPParameters to store FTP server name, user, password and directory (4 strings). Next create a setup form for the AifFTPParameters table and a display menu item. Add an OK command button. Add this code to the buttons clicked event:

    void clicked()
        // use the server name as selected value 

    FTP Parameters setup

  • Create a new AifFTPSendAdapter class that implementes the AifSendAdapter interface. You may create empty implementations for begin(), commit(), initialize(), rollback() and terminate(). But you really need to implement the sendMessage() method. I’m using the System.Net Classes to implement the FTP transfer.

    public void sendMessage(AifGatewayMessage gatewayMessage)
        System.Text.Encoding encoding;
        System.Byte[] bytes;
        str requestStr = "";
        object ftpo;
        System.Net.FtpWebRequest ftpRequest;
        System.Net.NetworkCredential credential;
        str ftpUser;
        str ftpPass;
        System.IO.Stream requestStream;
        InteropPermission clrPermission =
         new InteropPermission(InteropKind::ClrInterop);


            case ‘UTF-8’:
                encoding = System.Text.Encoding::get_UTF8();
                throw error("Unsupported Encoding");
        bytes = encoding.GetBytes(gatewayMessage.parmMessageXml());

        requestStr = strfmt(‘ftp://%1′,AifFTPParameters::find().ServerName);
            requestStr = strfmt(‘%1/%2’,

        requestStr = strfmt(‘%1/%2%3’,

        ftpo =  System.Net.WebRequest::Create(requestStr);
        ftpRequest = ftpo;

        ftpUser = AifFTPParameters::find().UserName;
        ftpPass = AifFTPParameters::find().Password;
        //BP deviation documented
        credential = new System.Net.NetworkCredential(ftpUser,ftpPass);

        requestStream = ftpRequest.GetRequestStream();


  • Create a new AifFTPAdapter class that implements AifIntegrationAdapter. This class is used by the AIF configuration interface in Dynamics AX to identify an outbound adapter and its configuration form.

    public AifIntegrationAdapterType getAdapterType()
        return AifIntegrationAdapterType::SendOnly;

    public MenuItemNameDisplay getAddressDisplayMenuItem()
        // the AifFTPParameter forms display menu items name
        return ‘AifFTPParameters’;

    public AifTransportAddress getCanonicalTransportAddress(AifTransportAddress transportAddress)
        return transportAddress;

    public MenuItemNameDisplay getConfigurationDisplayMenuItem()
        return ”;

    public LabelString getLabel()
        return "AIF FTP Adapter";

    public AifReceiveAdapter getReceiveAdapter()
        return null;

    public AifSendAdapter getSendAdapter()
        return new AifFTPSendAdapter();

    public boolean isHosted()
        return true;

    public void validateConfiguration(AifTransportAddress transportAddress,
                                      AifChannelDirection channelDirection)
        //TODO:Check or throw error

      1. Register FTP Adapter and configure AIF

    1. Go to Basics > Setup > Application Integration Framework.
    2. In Local Endpoints make sure you have an endpoint configured
    3. In Transport Adapters create a new record, select AifFTPAdapter and mark it as active.
    4. In Channels, create a new outbound FTP Channel, provide server name and credentials.
      Mark the channel as active.
      Configure AIF FTP Adapter 
    5. In Services activate the SalesSalesInvoiceService
      Activate SalesSalesInvoiceService 
    6. In Endpoints create a new endpoint. Set the outbound channel to your FTP channel and set the local endpoint. Go to the Constraints tab and set “No Constraints” flag. Mark the endpoint as active.
      Create an endpoint with outbound FTP

      Click the Action Policies button and add the method

      Click the Data Policies button and use the set button to enable all data fields for transportation.
      Set data policies for invoice

    7. Go to Basic > Inquiries > Batch jobs. Make sure to run a batch job that processes the AIF message send and receive tasks: AIFInboundProcessingService, AIFOutboundProcessingService, AIFGatewaySendService and AIFGatewayReceiveService.
      Setup AIF processing batch jobs
    8. Go to Accounts Receivable > Inquiries > Journals > Invoice. Select an invoice and use the Send Electronically button to put it in the transportation queue.
      Send invoice electronically using AIF
    9. Wait a few miniutes and take a look at your FTP space. There you should see the transmitted invoices as xml file.
      Invoice successfully uploaded

    AX 4.0 Send GUID in AIF document

    I’ve noticed a a bug in AX 4.0 (K/A: 4.0.2501.116) AIF implementation when using a table field type GUID. Unfortunately the generated XSD schema referred to the field type as Int64 instead of GUID. The sent XML of course contained an GUID String {00000000-1234-5678-9101-000000000000}. My C# .NET client reported an error because the received value was not a valid Int64.
    I solved the problem by editing AxdBaseGenerateXSD.addGuid() method
    protected void addGuid(
    SysDictType dt,
    XmlSchemaSimpleTypeRestriction restriction
    /*  restriction.baseTypeName(
    targetNameSpace)); */
    restriction.baseTypeName (XmlQualifiedName::construct(
    As result the generated XSD schema contained the correct GUID definition
    <xs:simpleType name=”AxdExtType_MyGUID“>
    <xs:documentation xml:lang=”DE-AT“>A Guid field</xs:documentation>
    <xs:restriction base=”AxdType_GUID” />

    <xs:simpleType name=”AxdType_GUID“>
    <xs:restriction base=”xs:string“>
    <xs:minLength value=”38” />
    <xs:maxLength value=”38” />
    value=”({[A-Fa-f0-9]{8}-[A-Fa-f0-9]{4}-[A-Fa-f0-9]{4}-[A-Fa-f0-9]{4}-[A-Fa-f0-9]{12}})” />
