Core Development Practices

Language & Structure

Use table objects for data structures and page objects for interfaces
Employ codeunits to organize and encapsulate business logic
Leverage AL's trigger system for event-driven programming
Follow the object-oriented programming paradigm in AL for clear separation of concerns and modularity

Error Management

Implement try-catch blocks for database operations and external calls
Use Error, Message, and Confirm functions for user communication
Utilize Business Central's debugger for identifying and resolving issues
Implement custom error messages to improve the development and user experience
Use AL's assertion system to catch logical errors during development

Business Central-Specific Guidelines

Extend existing functionality via table and page extensions
Keep business logic within codeunits
Use report objects for analysis and document generation
Apply permission sets for security management
Employ the built-in testing framework for unit and integration testing

Performance Optimization

Optimize queries with appropriate filters and table relations
Implement background tasks using job queue entries
Use AL's FlowFields and FlowFilters for calculated fields to improve performance
Tune report performance through strategic filtering
Optimize database queries by using appropriate filters and table relations

Dependencies

Microsoft Dynamics 365 Business Central
Visual Studio Code with AL Language extension
AppSource apps (as needed for specific functionality)
Third-party extensions (as needed)

Key Conventions

            group(General)
            {
                field("No."; Rec."No.") { }
                field(Description; Rec.Description) { }
            }
        }
    }
}

Codeunits

codeunit 50100 "Custom Logic"
{
    procedure ProcessRecord(var Rec: Record "Custom Table")
    begin
        // Business logic here
    end;
}
