You must follow the guidelines in this article only if you're using Microsoft Dynamics 365 Commerce version 10.0.28 or earlier. As of Commerce version 10.0.29, the fiscal registration service integration sample for Germany is available in the Commerce software development kit (SDK). For more information, see Configure channel components.

This article provides guidelines for deploying the fiscal registration service integration sample for Germany from the Dynamics 365 Commerce Retail SDK on a developer virtual machine (VM) in Microsoft Dynamics Lifecycle Services (LCS). For more information about this fiscal integration sample, see Fiscal registration service integration sample for Germany.

The fiscal integration sample for Germany is part of the Retail SDK. For information about how to install and use the SDK, see Retail software development kit (SDK) architecture. This sample consists of extensions for the Commerce runtime (CRT) and Hardware station. To run this sample, you must modify and build the CRT and Hardware station projects. We recommend that you use an unmodified Retail SDK to make the changes that are described in this article. We also recommend that you use a source control system such as Azure DevOps where no files have been changed yet.

Design of extensions

The fiscal registration service integration sample for Germany is based on the fiscal integration functionality. For more information about the design of the fiscal integration solution, see the overview of a fiscal integration sample design.

Commerce runtime extension design

The purpose of the extension that is a fiscal document provider is to generate service-specific documents and handle responses from the fiscal registration service.

The CRT extension is Runtime.Extensions.DocumentProvider.EFRSample. For more information about the design of the fiscal integration solution, see Overview of fiscal integration for Commerce channels.

Request handler

There is one request handler for the document provider, DocumentProviderEFRFiscalDEU. This handler is used to generate fiscal documents for the fiscal registration service. It's inherited from the INamedRequestHandler interface. The HandlerName method is responsible for returning the name of the handler. The handler name should match the connector document provider name that is specified in Commerce headquarters.

The connector supports the following requests:

  • GetFiscalDocumentDocumentProviderRequest – This request contains information about what document should be generated. It returns a service-specific document that should be registered in the fiscal registration service.
  • GetFiscalTransactionExtendedDataDocumentProviderRequest – This request returns the response together with extended data.

Configuration

The DocumentProviderFiscalEFRSampleGermany configuration file is located in the Configuration folder of the extension project. The purpose of this file is to enable settings for the document provider to be configured from Commerce headquarters. The file format is aligned with the requirements for fiscal integration configuration.

The following settings are added:

  • VAT rates mapping – The mapping of tax percentage values that are set up for the sales tax codes to values of the TaxG (tax group) attribute in requests that are sent to the fiscal service.
  • Tax group for gift cards and deposits – The value of the TaxG attribute in requests that are sent to the fiscal service, based on operations that involve gift cards or deposits.
  • Tender type mapping – The mapping of payment methods to values of the PayG (payment group) attribute in requests that are sent to the fiscal service.
  • Tax group for VAT exempt – The value of the TaxG attribute in requests that are sent to the fiscal service, based on operations that are exempt from tax obligations.
  • Include customer data – If this parameter is turned on, requests to the fiscal service will contain customer information, such as names and addresses, in cases where a customer is added to a transaction.

Hardware station extension design

The purpose of the extension that is a fiscal connector is to communicate with the fiscal registration service.

The Hardware station extension is HardwareStation.Extension.EFRSample. It uses the HTTP protocol to submit documents that the CRT extension generates to the fiscal registration service. It also handles the responses that are received from the fiscal registration service.

Request handler

The EFRHandler request handler is the entry point for handling requests to the fiscal registration service. This handler is inherited from the INamedRequestHandler interface. The HandlerName method is responsible for returning the name of the handler. The handler name should match the fiscal connector name that is specified in Commerce headquarters.

The connector supports the following requests:

  • SubmitDocumentFiscalDeviceRequest – This request sends documents to the fiscal registration service and returns a response from it.
  • IsReadyFiscalDeviceRequest – This request is used for a health check of the fiscal registration service.
  • InitializeFiscalDeviceRequest – This request is used to initialize the fiscal registration service.

Configuration

The configuration file is located in the Configuration folder of the extension project. The purpose of the file is to enable settings for the fiscal connector to be configured from Commerce headquarters. The file format is aligned with the requirements for fiscal integration configuration.

The following settings are added:

  • Endpoint address – The URL of the fiscal registration service.
  • Timeout – The amount of time, in milliseconds (ms), that the driver will wait for a response from the fiscal registration service.
  • Show fiscal registration notifications – If this parameter is turned on, notifications from the fiscal service will be shown as user messages at the POS.

POS fiscal connector extension design

The purpose of the POS fiscal connector extension is to communicate with the fiscal registration service from POS. It uses the HTTPS protocol for communication.

Fiscal connector factory

The fiscal connector factory maps the connector name to the fiscal connector implementation and is located in the Pos.Extension\Connectors\FiscalConnectorFactory.ts file. The connector name should match the fiscal connector name that is specified in Commerce headquarters.

EFR fiscal connector

The EFR fiscal connector is located in the Pos.Extension\Connectors\Efr\EfrFiscalConnector.ts file. It implements the IFiscalConnector interface that supports the following requests:

  • FiscalRegisterSubmitDocumentClientRequest – This request sends documents to the fiscal registration service and returns a response from it.
  • FiscalRegisterIsReadyClientRequest – This request is used for a health check of the fiscal registration service.
  • FiscalRegisterInitializeClientRequest – This request is used to initialize the fiscal registration service.

Configuration

The configuration file is located in the src\FiscalIntegration\Efr\Configurations\Connectors folder of the Dynamics 365 Commerce Solutions repository. The purpose of the file is to enable settings for the fiscal connector to be configured from Commerce headquarters. The file format is aligned with the requirements for fiscal integration configuration. The following settings are added:

  • Endpoint address – The URL of the fiscal registration service.
  • Timeout – The amount of time, in milliseconds, that the connector will wait for a response from the fiscal registration service.
