Enable master data lookup for tax calculation configuration

This article explains how to set up and enable the tax calculation master data lookup functionality. A dropdown list is available to select values in the tax calculation configuration for fields such as Legal entity, Vendor account, Item code, and Delivery term. These values come from the connected Microsoft Dynamics 365 Finance environment using the Microsoft Dataverse data source.

If you're using version 10.0.39 or later, follow these steps in Finance to enable the dropdown list in the feature version configuration of Tax Calculation.

1. In the Feature management workspace, enable the Enable applicability rules value lookup for Tax Calculation Service feature.

2. Make sure that you imported the latest configuration and model mapping versions. If you didn't, follow the steps in Import Electronic reporting (ER) configurations from Dataverse to import them.

   • Tax Data Model.version.40.xml
   • Tax Calculation Data Model 40.65.xml
   • FNO Model Mapping 40.65.35.xml (For this model mapping, set the Default for model mapping parameter to Yes.)
   • Tax Calculation Configuration 40.65.249.xml

3. On the tax Feature version setup page, select configuration version 40.65.249.

   Note

   If you have a customized configuration, you must rebase the configuration and then use the customized configuration.

4. In the Source legal entity field, select legal entities. You'll be able to choose master data from these legal entities.

If you're using version 10.0.38 or earlier, follow these steps to enable the dropdown list in the feature version configuration of Tax Calculation.

1. Enable Microsoft Power Platform integration and open the Dataverse environment.
2. Install finance and operations virtual entities.
3. Register a Microsoft Entra application.
4. Grant app permissions in finance and operations apps.
5. Configure the virtual entity data source.
6. Enable Dataverse virtual entities.
7. Set up the connected application for Tax Calculation.
8. Import and set up the Dataverse Model Mapping configuration.

Enable Microsoft Power Platform integration and open the Dataverse environment

The integration of finance and operations apps with Microsoft Power Platform can be enabled when you create a new finance and operations apps environment in Microsoft Dynamics Lifecycle Services. For more information, see Microsoft Power Platform integration - Add-ins overview. When you've finished, the name of a Microsoft Power Platform environment will appear in the Power Platform Integration section.

1. In Lifecycle Services, in your finance and operations environment, in the Power Platform Integration section, find and make a note of the Environment name value for the linked environment.

   

2. In the Power Platform admin center, on the Environments tab, select the environment that matches the Environment name value that you made a note of.

3. On the Details page, find the Environment URL value of the Dataverse environment. Make a note of this value, because you will need it in Step 7. Set up the connected application for Tax Calculation.

4. Make sure that you can open the Dataverse environment in your browser by selecting the Environment URL value.

   

   Note

   Keep the Dataverse environment open in your browser. You will need it in Step 5. Configure the virtual entity data source.

For more information, see Enable the Microsoft Power Platform integration.

Install finance and operations virtual entities

The Dataverse solution for finance and operations virtual entities must be installed from Microsoft AppSource virtual entity solution.

1. In AppSource, find the Finance and operations virtual entity.
2. Select Get it now.
3. In the Select an environment field, enter the Environment name value that you made a note of earlier.
4. Select the checkboxes, and then select Install.

When the installation is completed, you can find the Finance and operations virtual entity app in the Power Platform admin center, under Resources > Dynamics 365 apps.

For more information, see Getting the virtual entity solution.

Register a Microsoft Entra application

You must register a Microsoft Entra application on the same tenant as the finance and operations apps, so that they can be called by Dataverse.

1. In the Azure portal, go to Microsoft Entra > App registrations.

2. Select New registration, and enter the following information:

   • Name – Enter a unique name.
   • Account type – Enter Any Microsoft Entra directory (single-tenant or multi-tenant).
   • Redirect URI – Leave this field blank.

3. Select Register.

4. Make a note of the Application (client) ID value, because you will need it later.

   

5. Create a symmetric key for the application.

6. In the new application, select Certificates & secrets.

7. Select New client secret.

8. Enter a description, select an expiration date, and then select Save. A key will be created and shown. Copy the value for later use.

For more information, see Register Microsoft Entra application.

Grant app permissions in finance and operations apps

Dataverse uses the Microsoft Entra application that you created to call finance and operations apps. Therefore, the application must be trusted by the finance and operations apps and associated with a user account that has the appropriate rights. In the finance and operations apps, you must create a special service user that has rights only to the virtual entity functionality. This service user must have no other rights. After you complete this step, any application that has the secret of the Microsoft Entra application that you created will be able to call the finance and operations apps environment and access the virtual entity functionality.

1. In your environment, go to System Administration > Users > Users.

2. Select New to add a new user, and enter the following information:

   • User ID – Enter dataverseintegration or another value.
   • User name – Enter dataverse integration or another value.
   • Provider – Set this field to NonMicrosoft Entra ID.
   • Email – Enter dataverseintegration or another value. (The value doesn't have to be a valid email account.)

3. Assign the Dataverse Virtual entity integration app security role to the user.

4. Remove all other roles, including System user.

5. Go to System Administration > Setup > Microsoft Entra applications to register Dataverse.

6. Add a row, and then, in the Client ID field, enter the Application (client) ID value that you made a note of earlier.

7. In the Name field, enter a name. For example, enter Dataverse Integration.

8. In the User ID field, enter the user ID that you created earlier.

For more information, see Grant app permissions in Finance and Operations apps.

Configure the virtual entity data source

You must provide Dataverse with the finance and operations app instance to connect to.

1. Your Dataverse environment should still be open in your browser from Step 1. Enable Microsoft Power Platform integration and open the Dataverse environment. Select the settings button (gear symbol) in the upper right, and then select Advanced Settings.

   

2. On the Settings dropdown menu, select Administration.

   

3. Select Virtual Entity Data Sources.

   

4. Select the data source that is named Finance and Operations.

   

5. Enter the following information from earlier steps:

   • Target URL – Enter the URL where you can access finance and operations apps.
   • OAuth URL – Enter https://login.windows.net/.
   • Tenant ID – Specify your tenant. This value can be the domain name of your company email (such as contoso.com).
   • Microsoft Entra Application ID – Enter the Application (client) ID value that was created earlier.
   • Microsoft Entra Application Secret – Enter the secret that was generated earlier.
   • Microsoft Entra Resource – Enter 00000015-0000-0000-c000-000000000000. This value is the Microsoft Entra application that represents finance and operations apps. It should always be this same value.

6. Save your changes.

7. Close the page to return to the Administration page, where you will begin Step 6. Enable Dataverse virtual entities.

   

For more information, see Configure the virtual entity data source.

Enable Dataverse virtual entities

The visibility of the virtual entities from finance and operations apps must be set to Yes before they can be consumed by the Tax Calculation configuration.

1. In your Dataverse environment, on the Administration page, select the filter button (funnel symbol) in the upper-right corner.

   

2. In the Advanced find window, in the Look for field, select Available Finance and Operations Entities.

3. Add the following rule: Name – Contains – CompanyInfoEntity. Then select Results.

   

4. Select CompanyInfoEntity in the search results, select the Visible checkbox, and then select Save.

   

5. Repeat the preceding steps for the following entities that are referred to in the Tax Calculation configuration:

   • CompanyInfoEntity
   • CurrencyEntity
   • CustCustomerV3Entity
   • DeliveryTermsEntity
   • EcoResProductCategoryEntity
   • EcoResReleasedProductV2Entity

   • Tax Service Dataverse datasources support

Import and set up the Dataverse Model Mapping configuration

Microsoft provides default model mapping configurations for entities from finance and operations apps to Tax Calculation.

1. In RCS, go to Electronic reporting.

2. In the Configuration providers section, on the tile for the Microsoft provider, select Repositories.

   

3. Select the Global configuration repository record, and then select Open.

4. Under Tax Data Model > Tax Calculation Data Model, select the Dataverse Model Mapping configuration.

5. On the Versions FastTab, select a version that matches your finance and operations apps version, and then select Import.

   

   Important

   The Dataverse Model Mapping configuration is effective only on its highest imported version. Therefore, you should not import a version of the Dataverse Model Mapping configuration that is higher than the version of the Tax Calculation configuration that you plan to implement. For example, if you plan to implement version 40.50.225 of the Tax Calculation configuration, you should import only version 40.50.13 of the Dataverse Model Mapping configuration. You should not import version 40.54.14. Otherwise, there will be a data model mismatch in the configuration.

6. Go back to Electronic reporting, and select the Tax configurations tile.

7. Select the imported Dataverse Model Mapping configuration, and then select Edit.

8. Set the Default for model mapping option to Yes.

9. In Connected application field, select the connected application that you set up in Step 7. Set up the connected application for Tax Calculation.

10. Set the Set virtual table visibility option to Yes to set all Tax Calculation–related virtual entities to visible.

You've now completed the setup for the master data lookup functionality. A dropdown list for fields such as Legal entity, Vendor account, Item code, and Delivery term from Dynamics 365 Finance will now be enabled in the Tax Calculation feature version setup.
