Overview

This section is the reference for AL object types. Most pages cover one object: its purpose, syntax, main properties and triggers. A properties overview and a page on table keys support them. Data objects include table, table extension, query, report and XMLport. UI objects include page, page extension, page customization and control add-in. Logic is held in codeunits, including test codeunits and test runner codeunits. Profiles, permission sets and entitlements define user experiences and access.

Key points

• AL Properties Overview explains how properties control the behavior of objects and elements such as fields, actions, data items and columns. Start there for general property concepts.
• Table and table extension objects cover fields, keys, triggers and the Extensible property. Table keys covers primary, secondary, unique and clustered keys, and IncludedFields.
• Page objects use SourceTable, layout sections, actions and views. Page extensions change pages with the addfirst, addlast, addafter, addbefore, modify, movefirst, movelast, moveafter and movebefore keywords.
• Page customization changes layout and actions only for specified profiles, with no variables, procedures or triggers. It is more limited than a page extension.
• Profile and profile extension objects set a role center and optional page customizations for a user experience.
• Permission set and permission set extension objects define and compose permissions. They use Assignable, IncludedPermissionSets and ExcludedPermissionSets. Extensions can add permissions to existing sets.
• Entitlement objects define which objects customers can use based on licenses or Microsoft Entra roles. They support Marketplace app transactability.
• Test codeunits and test runner codeunits cover test methods, handlers, TransactionModel and TestIsolation. Runners add OnBeforeTestRun and OnAfterTestRun for unattended runs.
