Fiscal registration service integration sample for the Czech Republic

  • Grein

This article provides an overview of the fiscal integration sample for the Czech Republic in Microsoft Dynamics 365 Commerce.

To meet local fiscal requirements for cash registers in the Czech Republic, the Dynamics 365 Commerce functionality for the Czech Republic includes a sample integration of the point of sale (POS) with an external fiscal registration service. The sample extends the fiscal integration functionality. It's based on the EFR (Electronic Fiscal Register) solution from EFSTA and enables communication with the EFR service via the HTTPS protocol. The EFR service ensures Electronic Registration of Sales (Elektronická evidence tržeb [EET]). In other words, it ensures online transmission of the sales data to a fiscal web service of tax authorities. The EFR service should be hosted on either the Commerce Hardware station or a separate machine that can be connected to from the Hardware station. The sample is provided in the form of source code and is part of the Commerce software development kit (SDK).

Microsoft doesn't release any hardware, software, or documentation from EFSTA. For information about how to get the EFR solution and operate it, contact EFSTA.

Scenarios

The following scenarios are covered by the fiscal registration service integration sample for the Czech Republic.

  • Registration of cash transactions in the fiscal registration service.

    • Send detailed transaction data to the fiscal registration service. This data includes sales line information, and information about discounts, payments, and taxes. The fiscal registration service further sends the data to the web-service of tax authorities and receives a confirmation from it that includes the fiscal identification code of the transaction.
    • Capture a response from the fiscal registration service. This response includes fiscal data such as the fiscal identification code and the security code of the transaction, etc.
    • Print the fiscal data for a registered transaction on the receipt.

  • Registration of gift card operations and customer deposits in the fiscal registration service.

    • Issue or add money to a gift card.
    • Register a customer account deposit.
    • Create a customer order and register a deposit for the order.
    • Edit a customer order and override the deposit for the order.
    • Cancel a customer order and refund the deposit for the order.

  • Error handling, such as the following options.

    • Retry fiscal registration if a retry is possible, such as if the fiscal registration service isn't available, isn't ready, or isn't responding.
    • Defer fiscal registration.
    • Skip fiscal registration, or mark the transaction as registered, and include info codes to capture the reason for the failure and additional information.
    • Check the availability of the fiscal registration service before a new sales transaction is opened or a sales transaction is finalized.

Gift cards

The fiscal registration service integration sample implements the following rules that are related to gift cards.

  • Sales lines that are related to the Issue gift card or Add to gift card operations in a sales transaction are marked with a special attribute when the transaction is registered in the fiscal registration service.
  • A payment by gift card is considered a regular payment and marked with a special attribute when the transaction is registered in the fiscal registration service.

Customer account deposits and customer order deposits

The fiscal registration service integration sample implements the following rules that are related to customer account deposits and customer order deposits.

  • A transaction that is related to a customer account deposit or a customer order deposit is registered in the fiscal registration service as a single line transaction and is marked with a special attribute. The deposit VAT group is specified in this line.
  • When a hybrid customer order is created, that is, a customer order that contains products that can be carried out of the store by the customer, as well as products that will be picked up or shipped later, the transaction registered in the fiscal registration service contains lines for the products that are carried out, as well as a line for the order deposit.
  • A payment from a customer account is considered a regular payment and marked with a special attribute when the transaction is registered in the fiscal registration service.
  • The customer order deposit amount that is applied to a customer order pickup operation is considered a regular payment and marked with a special attribute when the transaction is registered in the fiscal registration service.

Offline registration

If the fiscal registration service fails to transmit transaction data to the fiscal web service of tax authorities (for example, due to the response timeout) and to receive a confirmation from the web-service (that is, the fiscal identification code of the transaction), it generates a local signature for the transaction and includes it and a special error code in the response. The fiscal registration service resends transactions in original order in background as soon as the network connection is restored.

Limitations of the sample

The fiscal registration service supports only scenarios where sales tax is included in the price. Therefore, the Price include sales tax option must be set to Yes for both stores and customers.

Set up Commerce for the Czech Republic

This section describes the Commerce settings that are specific to and recommended for the Czech Republic. For more information, see Commerce home page.

To use the Czech-specific functionality, you must specify the following settings.

  • In the primary address of the legal entity, set the Country/region field to CZE (Czech Republic).
  • In the POS functionality profile of every store that is located in the Czech Republic, set the ISO code field to CZ (Czech Republic).

You must also specify the following settings for the Czech Republic. Note that you must run appropriate distribution jobs after you complete the setup.

Set up VAT per Czech Republic requirements

You must create sales tax codes, sales tax groups, and item sales tax groups. You must also set up sales tax information for products and services. For more information about how to set up and use sales tax features, see Sales tax overview.

Set up stores

On the All stores page, update the store details. Specifically, set the following parameters.

  • In the Sales tax group field, specify the sales tax group that should be used for sales to the default customer.
  • Set the Prices include sales tax option to Yes.
  • Set the Name field to the company name. This change helps guarantee that the company name appears on a sales receipt. Alternatively, you can add the company name to the sales receipt layout as free-form text.
  • Set the Tax identification number (TIN) field to the company identification number. This change helps guarantee that the company identification number appears on a sales receipt. Alternatively, you can add the company identification number to the sales receipt layout as free-form text.

Set up functionality profiles

Set up POS functionality profiles.

  • On the Receipt numbering FastTab, set up receipt numbering by creating or updating records for the Sale, Sales order, and Return receipt transaction types.

Set up registration numbers

  1. Go to Organization administration > Global address book > Registration types > Registration types. Create a new registration type. Specify the Country/region field to CZE (Czech Republic) and make it restricted to Organization.

  2. Go to Organization administration > Global address book > Registration types > Registration categories. Create a new registration category. Select the registration type from the previous step and set the Registration category to Business Premise ID.

  3. Go to Organization administration > Organizations > Operating units. For each store located in the Czech Republic, select the unit related to the store. On the Address FastTab expand the More options drop-down list and select Advanced.

  4. On the opened Manage addresses page you must specify the following settings:

    • On the Address FastTab set the Country/region field to CZE.
    • On the Registration ID FastTab create a new record. Select the registration type created earlier and set the registration number.

Configure custom fields so that they can be used in receipt formats for sales receipts

You can configure the language text and custom fields that are used in the POS receipt formats. The default company of the user who creates the receipt setup should be the same legal entity where the language text setup is created. Alternatively, the same language texts should be created in both the user's default company and the legal entity of the store that the setup is created for.

On the Language text page, add the following records for the labels of the custom fields for receipt layouts. Note that the Language ID, Text ID, and Text values that are shown in the table are just examples. You can change them to meet your requirements. However, the Text ID values that you use must be unique, and they must be equal to or more than 900001.

Add the following POS labels to the POS section of Language text from the table:

Language ID Text ID Text
en-US 900001 ID provozovny/pokladny
en-US 900002 BKP
en-US 900003 PKP
en-US 900004 FIK
en-US 900005 Info
en-US 900006 Sequence number

On the Custom fields page, add the following records for the custom fields for receipt layouts. Note that Caption text ID values must correspond to the Text ID values that you specified on the Language text page:

Name Type Caption text ID
TLT Receipt 900001
SEC Receipt 900002
SIGN Receipt 900003
FISCAL Receipt 900004
INFO Receipt 900005
CONTINUOUSNUMBER Receipt 900006

Note

It's important that you specify correct custom field names, as listed in the preceding table. An incorrect custom field name will cause missing data in receipts.

Design of extensions

The fiscal registration service integration sample for the Czech Republic is based on the fiscal integration functionality and is part of the Commerce SDK. The sample is located in the src\FiscalIntegration\Efr folder of the Dynamics 365 Commerce Solutions repository. The sample consists of a fiscal document provider, which is an extension of CRT, and a fiscal connector, which is an extension of Commerce Hardware Station. For more information about how to use the Commerce SDK, see Download Commerce SDK samples and reference packages from GitHub and NuGet and Set up a build pipeline for the independent-packaging SDK.

Note

The fiscal registration service integration sample for the Czech Republic is available in the Commerce SDK as of Commerce version 10.0.29. In Commerce version 10.0.28 or earlier, you must use the previous version of the Retail SDK on a developer VM in LCS. For more information, see Deployment guidelines for the fiscal integration sample for the Czech Republic (legacy).

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.

Request handler

There is a single DocumentProviderEFRFiscalCZE request handler for document provider, which is used to generate fiscal documents for 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 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.
  • GetSupportedRegistrableEventsDocumentProviderRequest – This request returns the list of events to subscribe to. Currently, the following events are supported: sales, customer account deposits and customer order deposits.
  • GetFiscalRegisterResponseToSaveDocumentProviderRequest – This request returns the response from the fiscal registration service. This response is serialized to form a string so that it's ready to be saved.

Configuration

The configuration file for the fiscal document provider is located at src\FiscalIntegration\Efr\Configurations\DocumentProviders\DocumentProviderFiscalEFRSampleCzech.xml in the Dynamics 365 Commerce Solutions repository. The purpose of the file is to enable settings of the fiscal document provider to be configured from Commerce headquarters. The file format is aligned with the requirements for fiscal integration configuration.

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 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.

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

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.
