Microsoft Dynamics Development, Extensions, and Deployment (MB6-894) Practice Exam

What are two best practices for extending data types in Microsoft Dynamics 365 for Finance and Operations?

1. An EDT should be created for each atomic entity being utilized.

2. Subtypes are not required for EDTs that do not contain any property changes.

3. You cannot extend the recID or tableID system data types.

4. You cannot use EDTs if one of them is a member of the parent extended data.

The correct answer is: An EDT should be created for each atomic entity being utilized.

Creating an Extended Data Type (EDT) for each atomic entity being utilized is a best practice because it promotes consistency and reusability throughout the application. EDTs serve as a way to define data types that can be used uniformly across various tables and fields, ensuring that data integrity is maintained and that similar data types are treated consistently within the system. By establishing EDTs for each atomic entity, developers can avoid duplication of code and make future changes easier, as updates to the EDT will propagate wherever it is used. Moreover, this approach encourages clear documentation of data types used within the application, facilitating better understanding and collaboration among developers and stakeholders. In scenarios where a specific atomic entity is represented as an EDT, it can enhance the readability and maintainability of the codebase, leading to fewer errors and a more robust development process. The other options provided touch on valid points regarding EDTs but do not represent best practices in the same way. It's essential to understand that best practices in this context aim to establish a predictable and efficient development environment in Microsoft Dynamics 365 for Finance and Operations.
