PEPPOL Sales Documents – Extension Points

The RSMSTA SalesInvPEPPOLBIS3.0 (XMLport 10058600) and RSMSTA SalesCrMemoPEPPOLBIS3.0 (XMLport 10058601) XMLports generate outbound PEPPOL BIS 3.0 sales invoices and credit memos. Both XMLports share a nearly identical structure and expose the same extension points unless noted otherwise.

There are three layers of extension points:

XMLport events — declared directly on the XMLport (namespace WiseCourier.Standard.eDocuments)
Courier events — raised by helper codeunits called during XMLport execution
PEPPOL Management events — standard BC events (namespace Microsoft.Sales.Peppol) that the XMLport delegates to for most data retrieval

Subscribe to these events in your own codeunit — no modification of the base XMLport is required.

The XMLports are responsible only for XML generation. Data validation does not occur inside the XMLport — it happens afterwards when the XML is submitted through the web service for delivery. Subscribers to these events can add or modify data freely without triggering validation errors at generation time.

XMLport events

`OnBeforeAdditionalItemPropertyLoop`

Fires once per line before writing AdditionalItemProperty elements. Call AddAdditionalItemPropertyToList() on the XMLport instance to inject name/value pairs that appear as <cac:AdditionalItemProperty> elements in the output.

This event uses [IntegrationEvent(true, false)] — the first parameter true means “include sender”, so the XMLport instance is the sender. You call AddAdditionalItemPropertyToList on that sender instance.

// Invoice
[EventSubscriber(ObjectType::XmlPort, XmlPort::"RSMSTA SalesInvPEPPOLBIS3.0",
    'OnBeforeAdditionalItemPropertyLoop', '', false, false)]
local procedure AddCustomItemProperties(SalesLine: Record "Sales Line")
var
    SalesInvXmlPort: XmlPort "RSMSTA SalesInvPEPPOLBIS3.0";
begin
    SalesInvXmlPort.AddAdditionalItemPropertyToList('Color', SalesLine."RSMSTA Color");
    SalesInvXmlPort.AddAdditionalItemPropertyToList('BatchNo', SalesLine."Lot No.");
end;

// Credit Memo — identical signature, different XMLport
[EventSubscriber(ObjectType::XmlPort, XmlPort::"RSMSTA SalesCrMemoPEPPOLBIS3.0",
    'OnBeforeAdditionalItemPropertyLoop', '', false, false)]
local procedure AddCustomItemPropertiesCrMemo(SalesLine: Record "Sales Line")
var
    SalesCrMemoXmlPort: XmlPort "RSMSTA SalesCrMemoPEPPOLBIS3.0";
begin
    SalesCrMemoXmlPort.AddAdditionalItemPropertyToList('Color', SalesLine."RSMSTA Color");
end;

`OnGetFinalDueDateClaim` (Invoice only)

Lets you override the <cbc:DueDate> element and/or inject an AdditionalDocumentReference entry with DocumentDescription = 'EINDAGI' (used for final due date claims in Icelandic invoicing).

Parameter	Direction	Effect
`ClaimDueDate`	`var Text` (YYYYMMDD)	Replaces `<cbc:DueDate>` in the XML
`ClaimFinalDueDate`	`var Text` (YYYYMMDD)	Adds an `AdditionalDocumentReference` with `ID = <date>` and description `EINDAGI`

[EventSubscriber(ObjectType::XmlPort, XmlPort::"RSMSTA SalesInvPEPPOLBIS3.0",
    'OnGetFinalDueDateClaim', '', false, false)]
local procedure SetFinalDueDateClaim(
    SalesHeader: Record "Sales Header";
    var ClaimFinalDueDate: Text;
    var ClaimDueDate: Text)
begin
    if SalesHeader."Payment Method Code" = 'CLAIM30' then begin
        ClaimDueDate := Format(SalesHeader."Due Date" + 30, 0, '<Year4><Month,2><Day,2>');
        ClaimFinalDueDate := Format(SalesHeader."Due Date" + 60, 0, '<Year4><Month,2><Day,2>');
    end;
end;

Courier events

These events are raised by helper codeunits called during XMLport execution. Subscribe on RSMSTA Wise Courier Events or RSMSTA EDocIntegrationHelpFunc as indicated.

`OnAfterGetDueDateForInvoice` (Invoice only)

Raised after the due date is resolved. Modify DueDate as an ISO 8601 text string before it is written to the XML.

[EventSubscriber(ObjectType::Codeunit, Codeunit::"RSMSTA Wise Courier Events",
    'OnAfterGetDueDateForInvoice', '', false, false)]
local procedure AdjustDueDate(var DueDate: Text; SalesHeader: Record "Sales Header")
begin
    if SalesHeader."Currency Code" = 'USD' then
        DueDate := Format(SalesHeader."Due Date" + 5, 0, 9);
end;

`CourierGetAccountingSupplierPartyPostalAddr`

Override the supplier postal address (street, city, postal zone, country).

[EventSubscriber(ObjectType::Codeunit, Codeunit::"RSMSTA Wise Courier Events",
    'CourierGetAccountingSupplierPartyPostalAddr', '', false, false)]
local procedure OverrideSupplierAddress(
    SalesHeader: Record "Sales Header";
    var StreetName: Text; var AdditionalStreetName: Text;
    var CityName: Text; var PostalZone: Text;
    var CountrySubentity: Text; var IdentificationCode: Text;
    var DummyListID: Text)
begin
    if SalesHeader."Responsibility Center" = 'WAREHOUSE' then begin
        StreetName := 'Warehouse Road 1';
        CityName := 'Reykjavik';
        PostalZone := '108';
        IdentificationCode := 'IS';
    end;
end;

`CourierGetAccountingSupplierPartyTaxSchemeBIS`

Override CompanyID, schemeID, and TaxSchemeID inside PartyTaxScheme for the supplier party.

`CourierOnBeforeGetAccountingSupplierPartyInfoByFormat` / `CourierOnAfterGetAccountingSupplierPartyInfoByFormat`

Override or modify the supplier EndpointID, SchemeID, and Name before/after the standard lookup runs.

`OnBeforeGetAdditionalDocRefInfoSalesInvoice` / `OnAfterGetAdditionalDocRefInfoSalesInvoice`

Control AdditionalDocumentReference entries on invoices — attachments, embedded PDFs, external URIs. The OnBefore variant has an IsHandled parameter to skip the standard logic entirely.

`OnBeforeGetAdditionalDocRefInfoSalesCrMemo` / `OnAfterGetAdditionalDocRefInfoSalesCrMemo`

Same as above for credit memos.

`OnBeforeCountAttachmentsSalesOrServiceInvoices` / `OnAfterCountAttachmentsSalesOrServiceInvoices`

Control how many AdditionalDocumentReference loop iterations are created on invoices. Use this to add extra attachment slots beyond what the standard logic allocates.

`OnBeforeCountAttachmentsCrMemoOrServiceInvoices` / `OnAfterCountAttachmentsCrMemoOrServiceInvoices`

Same as above for credit memos.

`OnAfterGetPaymentMeansPayeeFinancialAccBISInternal`

Override the PayeeFinancialAccount (IBAN) and FinancialInstitutionBranch (SWIFT/BIC) inside the XMLport’s PaymentMeans section. This fires from the XMLport directly and takes precedence over the bank account lookup from the RSMSTA Use for e-Invoice flag.

[EventSubscriber(ObjectType::Codeunit, Codeunit::"RSMSTA EDocIntegrationHelpFunc",
    'OnAfterGetPaymentMeansPayeeFinancialAccBISInternal', '', false, false)]
local procedure OverrideBankAccountInternal(
    SalesHeader: Record "Sales Header";
    var PayeeFinancialAccountID: Text;
    var FinancialInstitutionBranchID: Text)
begin
    if SalesHeader."Currency Code" = 'EUR' then begin
        PayeeFinancialAccountID := 'IS140159260076545510730339';
        FinancialInstitutionBranchID := 'NBIIISREXX';
    end;
end;

`OnBeforeCreateSalesInvoiceXML` / `OnAfterCreateSalesInvoiceXML`

Intercept the entire XML generation pass for invoices.

OnBefore — fires before the XMLport runs. Set IsHandled := true to completely replace XML generation with your own logic.
OnAfter — fires after the XMLport has written the XML into a TempBlob. Post-process the blob directly (e.g., inject custom namespaces or elements via DOM manipulation).

`OnBeforeCreateSalesCrMemoXML` / `OnAfterCreateSalesCrMemoXML`

Same as above for credit memos.

PEPPOL Management events

The XMLports call PEPPOL Management (codeunit 1605) for most data retrieval. Subscribe to its events to override individual fields without touching the XMLports. These events apply to both invoices and credit memos unless noted.

Invoice header

`OnAfterGetGeneralInfo` — Note, TaxPointDate, AccountingCost, InvoiceTypeCode

[EventSubscriber(ObjectType::Codeunit, Codeunit::"PEPPOL Management",
    'OnAfterGetGeneralInfo', '', false, false)]

    var Note: Text; var TaxPointDate: Text;

Inject or modify AdditionalDocumentReference entries at the PEPPOL Management level (document attachments from the Document Attachment table).

[EventSubscriber(ObjectType::Codeunit, Codeunit::"PEPPOL Management",
    'OnAfterGetAdditionalDocRefInfo', '', false, false)]
local procedure AttachDeliveryNoteURI(

Invoice lines

`OnAfterGetLineGeneralInfo` — Note, quantity, extension amount, AccountingCost
