MB-920: Microsoft Dynamics 365 Fundamentals (ERP) - Quiz

Acoustics plays a crucial role in industrial production by enabling the identification of sound-related defects, ensuring product quality, and enhancing safety measures. By utilizing acoustics, manufacturers can detect potential issues and improve the overall production process.

When you extend a data entity in Dynamics 365 Finance (for example, by adding new fields), these changes may not appear immediately in the Data Management framework.

To make the changes visible and usable, you need to:

✔ Use the "Refresh entity list" function in the Data Management workspace.

This action:

• Refreshes metadata for all data entities.

• Ensures that the new fields or extensions are recognized by the system.

• Makes the entity ready for further actions like export, import, or mapping.

❌ Incorrect Options:

• Truncate entity list
  ❌ Deletes records from the staging or execution tables — not related to metadata or field visibility.

• Generate mapping
  ❌ Used after the entity is already recognized and you're mapping source/target fields, but won't make new fields visible if the entity list isn’t refreshed first.

• Configure entity execution parameters
  ❌ Deals with execution settings (like batch size), not metadata or visibility of new fields.

✅ Final Answer:

✔ Refresh entity list

The correct answer is:

✅ Service group

✅ Explanation:

To expose a JSON-based custom web service in Dynamics 365 Finance, you need to:

Create a service class and expose it through a Service group AOT element.

Why Service group?

• A Service group:

  • Is used to publish custom services to be consumed externally.

  • Supports RESTful endpoints and returns data in JSON format.

  • Can contain one or more Service classes (with [SysODataAction] or [SysODataCollection] attributes).

This is the correct approach when you need custom business logic exposed to external applications through JSON-based APIs.

❌ Incorrect Options:

• Data entity
  ❌ Used for data import/export and OData endpoints, but not suitable for custom logic or service operations.

• Provider
  ❌ Not a specific AOT element used for creating custom JSON services.

• Macro
  ❌ Used for compile-time constants or conditional code, unrelated to services or integrations.

✅ Final Answer:

✔ Service group

The correct answers are:

✅ 1. REST-based custom service

• You can create a REST-based custom service in Dynamics 365 Finance to:

  • Expose budget validation logic.

  • Return the allocated budget for a given account and dimension.

  • Use JSON as the response format (REST = JSON).

• ✔️ Meets both real-time integration and JSON format requirements.

✅ 2. Execute action in the Power Automate Fin & Ops connector

• Power Automate’s Finance and Operations connector allows you to call actions (including custom services) exposed from F&O.

• You can configure a Power Automate flow to:

  • Send the request (account + dimension).

  • Get the response in JSON.

• ✔️ Works well for low-code scenarios and integrates with third-party apps via Power Platform.

❌ Incorrect Options:

• .NET-based wrapper class to call a SOAP service
  ❌ SOAP services return data in XML, not JSON.
  ❌ Also more complex and not native to JSON-based third-party app integrations.

• Business event with a service bus endpoint
  ❌ Business events are event-driven and asynchronous, used for triggering notifications.
  ❌ Not suitable for real-time request/response scenarios like budget validation.

✅ Final Correct Answers:

• ✅ REST-based custom service

• ✅ Execute action in the Power Automate Fin & Ops connector

This item tests the candidate’s knowledge of navigating the finance and operations apps and how workspaces specifically are used to summarize and present an activity-oriented view of financial data.

Workspaces are used to provide a personalized work center of data, reports, and transactions that increase the efficiency of daily tasks. In the scenario, the manager could open the customer invoice workspace to get an overview of this information. The workspace would typically include a set of KPI tiles that you can select to drill through a set of relevant transaction lists for the activity and several links to pages.

A module is incorrect because selecting a module simply opens a specific page in that module. It does not provide a summarized overview of data.

Favorites is incorrect because this provides quick access to only the list of pages a user has explicitly marked as a favorite, not workspaces.

The Filters pane is incorrect because it only provides an easy-to-use interface for filtering full page lists. This falls outside of workspaces.

Tile is incorrect because tiles are components of dashboards and workspaces but alone do not fulfill the scenario. Tiles display relevant data, such as counts or KPIs.

This item tests the candidate’s knowledge of the general capabilities of the Dynamics 365 finance and operations apps.

Dynamics 365 Supply Chain Management includes the cost management module, which takes care of the valuation of the product. Dynamics 365 Commerce is not involved in the valuation of the product; it is focused on retail operations only. Dynamics 365 Field Service is responsible for allocating service jobs to the field engineers; it is not involved in the valuation of inventory items. Dynamics 365 Project Operations deals with project costing; it does not calculate the cost of inventory items.

This item tests the candidate’s knowledge of how to use data events for integrating Dynamics 365 Finance with Microsoft Dataverse and Microsoft Power Platform.

A data event enables external applications to receive notifications from finance and operations apps when events occur. A business event lets you use Microsoft Power Platform to respond to events that are occurring in Dynamics Finance apps. The SPED-Reinf was created to assess federal taxes that are withheld for the purpose of Social Security and income taxes, and for activities that are not related to labor. The MR-Logger event is what would export if you had problems with reports.

This item tests the candidate’s knowledge of the procure-to-pay process in Dynamics 365 Supply Chain Management and specifically the role and attributes of a purchase requisition. The use of a purchase requisition is correct because this is an internal document that authorizes the purchase department to procure the product, in this case the printer. The sales order is a commercial document that is shared externally with the customer. The purchase order is an agreement between a company and a vendor. An RFQ document is used to receive competitive offers from vendors for the items or services they need to purchase.

This item tests the candidate’s knowledge of making payments to international vendors by using the letter of credit functionality.

Letter of credit is a bank document that are commonly used for the purchase and sale of goods across international borders. In Dynamics 365 Finance, it is configured in the Cash and bank management module. Letter of credit is a bank document that is referenced in accounts payable for payment, but it is neither configured nor maintained in the Accounts payables module. The General ledger module maintains the chart of accounts to link the bank account. It does not maintain or create bank documents. Letter of credit is a bank document, which may be used to receive payment; it is neither configured nor maintained in the Accounts receivable module.
