AL (Application Language) is the custom programming language for Dynamics 365 Business Central, enabling developers to extend and tailor the ERP system to meet unique business needs. Building on its foundation in Microsoft’s legacy NAV system, AL allows for industry-specific customizations directly within Business Central.
Key Aspects of AL
- Specialized for Business Central Customization: Unlike Power Automate, which is designed for cross-platform workflow automation, AL is specifically for modifying ERP structures, adding workflows, and building extensions within Business Central.
- Object-Based Structure: AL works with core objects like Tables, Pages, Reports, and Code units, allowing developers to add custom fields, interfaces, and business logic without changing core application code.
- Event-Driven Customization: With an event-driven model, AL enables developers to trigger custom actions at specific workflow points, like when orders are submitted. This makes updates easier and minimizes disruption during Business Central upgrades.
- Modular Development with Extensions: AL customizations are packaged as extensions, keeping custom code separate from core Business Central, making deployment, scaling, and updates easier.
- Development in Visual Studio Code: AL is developed in Visual Studio Code using the AL Extension, with features like IntelliSense and debugging to streamline the process for those familiar with Microsoft tools.
AL is Ideal for ERP-specific customizations within Business Central, such as adding fields, creating custom modules, or extending core features. By mastering AL, developers can transform Business Central into a powerful, customized ERP solution that aligns perfectly with an organization’s needs.
