Developing by using AL objects is a fundamental skill for Microsoft Dynamics 365 Business Central developers. AL (Application Language) is the programming language used to create and modify functionality in Business Central. This topic covers various AL objects such as tables, pages, reports, codeunits, and queries. Developers need to understand how to create, modify, and extend these objects to customize and enhance Business Central applications. Key sub-topics include object properties, triggers, methods, and how to implement business logic using AL code. Additionally, developers should be familiar with AL syntax, data types, and best practices for writing efficient and maintainable code.

This topic is crucial to the overall MB-820 exam as it forms the foundation of Business Central development. Understanding AL objects and how to work with them is essential for creating custom solutions, integrating with other systems, and extending the functionality of Business Central. The ability to develop using AL objects is a core competency that ties into other exam topics such as application design, data management, and integration. Mastering this topic will provide candidates with the necessary skills to tackle more advanced development concepts and scenarios covered in the certification.

Candidates can expect a variety of question types related to developing with AL objects in the MB-820 exam:

  • Multiple-choice questions testing knowledge of AL syntax, object types, and their properties

Installing, developing, and deploying for Business Central involves setting up the development environment, creating and modifying extensions, and deploying solutions to various environments. This process includes configuring Visual Studio Code with the AL Language extension, setting up Docker containers for development, and understanding the AL programming language for creating custom functionality. Developers need to be proficient in creating and managing extensions, which can include new tables, pages, reports, and business logic. The deployment process involves publishing extensions to different environments, managing versioning, and understanding the differences between on-premises and cloud deployments.

This topic is crucial to the overall Microsoft Dynamics 365 Business Central Developer exam (MB-820) as it forms the foundation for all development work in Business Central. It relates directly to the core competencies required for a Business Central developer, including setting up the development environment, creating custom solutions, and managing the deployment process. Understanding these concepts is essential for successfully implementing and maintaining Business Central solutions, which is a key focus of the certification.

Candidates can expect a variety of question types on this topic in the actual exam:

  • Multiple-choice questions testing knowledge of development environment setup and configuration options
  • Scenario-based questions asking candidates to identify the correct steps for deploying an extension to a specific environment
  • Code-based questions requiring candidates to identify or complete AL code snippets for creating or modifying extensions
  • Troubleshooting questions related to common issues encountered during installation, development, or deployment processes
  • Questions on best practices for managing extensions and versioning in different deployment scenarios

The depth of knowledge required will range from basic understanding of concepts to practical application of skills in real-world scenarios. Candidates should be prepared to demonstrate their ability to make decisions about development and deployment strategies based on given requirements and constraints.
