Deployment guidelines for cash registers for France

Important

This topic applies to Dynamics 365 for Retail and Dynamics 365 for Finance and Operations.

This topic is a deployment guide that shows how to enable the Microsoft Dynamics 365 for Retail localization for France. The localization consists of several extensions of Retail components. For example, the extensions let you print custom fields on receipts, register additional audit events, sales transactions, and payment transactions in Point of Sale (POS), digitally sign sales transactions, and print X and Z reports in local formats. For more information about the Retail localization for France, see Cash registers for France.

This localization is part of the Retail software development kit (SDK). For information about how to install and use the Retail SDK, see the Retail SDK documentation.

This localization consists of extensions for the Commerce runtime (CRT), Retail Server, and POS. To run this sample, you must modify and build the CRT, Retail Server, and POS projects. We recommend that you use an unmodified Retail SDK to make the changes that are described in this topic. We also recommend that you use a source control system, such as Microsoft Visual Studio Online (VSO), where no files have been changed yet.

Storing a certificate for digital signing in Azure Key Vault

The digital signature extension uses a certificate that is installed in the local certificate storage of the machine where Retail Server is deployed. The thumbprint of the certificate must be specified in the configuration file (see the SequentialSignatureRegister component section later in this topic). Depending on the implementation topology, the certificate might have to be stored in Microsoft Azure Key Vault storage. The Retail localization for France contains a code sample that shows how to override the signing flow and sign sales transactions by using a certificate that is stored in Azure Key Vault storage.

Prerequisites

The following steps must be completed before you can use a certificate that is stored in Azure Key Vault storage:

  • The Azure Key Vault storage must be created. We recommend that you deploy the storage in the same geographical region as the Retail Server.
  • The certificate must be uploaded to the storage.
  • The Retail Server application must be authorized to read secrets from the storage.

For more information about how to work with Azure Key Vault, see Get started with Azure Key Vault.

Using the sample

The DigitalSignatureKeyVaultSample project contains sample code that uses a certificate that is stored in Azure Key Vault storage. To use the sample in a production environment, you must implement logic so that the following parameters can be specified in the HashAndSignData method of the CertificateSignatureServiceRequestHandler class:

  • Azure Key Vault URL – The URL of the Azure Key Vault storage.

    settings.Add(WellKnownKeyVaultSettings.KeyVaultUrl, "Set your Azure Key Vault URL here");
    
  • Client ID – An interactive client ID of the Azure Active Directory (Azure AD) application that is associated with the Azure Key Vault storage for authentication purposes. This client should have access to read secrets from the Azure Key Vault storage.

    settings.Add(WellKnownKeyVaultSettings.KeyVaultInteractiveClientId, "Set the client ID here");
    
  • Client secret – A secret key that is associated with the Azure AD application that is used for authentication in the Azure Key Vault storage.

    // Secret key value should be encrypted and stored in a safe place.
    settings.Add(WellKnownKeyVaultSettings.KeyVaultClientSecretKey, "Set the secret key here");
    
  • Secret reference – A secret reference to the certificate.

    SecretCertificate secretCertificate = settingsHelper.SecretProvider.GetSecret("vault:///{Specify the secret reference}") as SecretCertificate;
    

To override the signing flow, follow these steps.

  1. Build the DigitalSignatureKeyVaultSample project, and copy the Contoso.Commerce.Runtime.DigitalSignatureKeyVaultSample.dll assembly to the bin\ext Retail Server folder.

  2. Update the commerceRuntime.ext.config file by adding the following line to the composition section.

    <add source="assembly" value="Contoso.Commerce.Runtime.DataSignatureKeyVaultSample" />
    

Note

The thumbprint of the certificate that is used for digital signing should be specified in the configuration file of the SequentialSignatureRegister assembly, even if the certificate is stored in Azure Key Vault storage. For more information, see the SequentialSignatureRegister component section later in this topic.

Specifying application attributes that will be printed on receipts

You can use custom fields to print the following application attributes on receipts:

  • Build number – The software version of the POS application. By default, the value should equal the POS build number that Microsoft assigned to the POS application.

  • Certificate category and Certificate number – The category and number of the certificate of compliance that an accredited body issues for the application. By default, the values equal the category and the number of the certificate that is granted to Microsoft:

    • Microsoft Dynamics 365 for Finance and Operations:

      • Certificate category: C
      • Certificate number: 18/0202
    • Microsoft Dynamics 365 for Retail:

      • Certificate category: B
      • Certificate number: 18/0203

    Note

    By default, the certificate category and number that are assigned to Finance and Operations are printed. If you're implementing Retail, you must override the certificate category and number.

If you customize the POS application, and your customizations affect the compliance of the application, you might have to request a new certificate of compliance from an accredited body. In this case, you must override the build number, and the certificate category and number. Otherwise, the default values for the certificate category and number will be printed, but you must still specify the POS build number that Microsoft assigned to the POS application.

Overriding the build number

The software version/build number and publisher are specified in RetailSDK\BuildTools\Customization.settings.

<CustomVersion Condition="'$(CustomVersion)' == ''">1.0.0.1</CustomVersion>
<CustomName Condition="'$(CustomName)' == ''">Contoso Retail Customization</CustomName> 
<CustomDescription Condition="'$(CustomDescription)' == ''">Contoso Retail Customization</CustomDescription>
<CustomPublisher Condition="'$(CustomPublisher)' == ''">CN=Contoso Ltd.</CustomPublisher>
<CustomPublisherDisplayName Condition="'$(CustomPublisherDisplayName)' == ''">Contoso Ltd.</CustomPublisherDisplayName>
<CustomCopyright Condition="'$(CustomCopyright)' == ''">Copyright © 2016</CustomCopyright>

Overriding the certificate category and number

The certificate category and number are specified in RetailSDK\SampleExtensions\CommerceRuntime\Extensions.ReceiptsFrance\GetSalesTransactionCustomReceiptFieldService.

/// <summary>
/// Certification category.
/// </summary>
private const string CertificationCategory = "C";

/// <summary>
/// Certificate number.
/// </summary>
private const string CertificateNumber = "18/0202";

Note

You must also override the certificate category and number if you're implementing Retail. In this case, use the certificate category and number that are provided in the Specifying application attributes that will be printed on receipts section earlier in this topic.

Enable the digital signature in offline mode for Modern POS

To enable the digital signature in offline mode for Modern POS, you must follow these steps after you activate Modern POS on a new device.

  1. Sign in to POS.
  2. On the Database connection status page, make sure that the offline database is fully synchronized. When the value of the Pending downloads field is 0 (zero), the database is fully synchronized.
  3. Sign out of POS.
  4. Wait a while for the offline database to be fully synchronized.
  5. Sign in to POS.
  6. On the Database connection status page, make sure that the offline database is fully synchronized. When the value of the Pending transactions in offline database field is 0 (zero), the database is fully synchronized.
  7. Restart Modern POS.
