## Properties

| Property | Value |
|---|---|
| Caption | Application Area |
| SourceTable | Application Area Buffer |
| PageType | List |
| UsageCategory | Tasks |
| ApplicationArea | All |

## Fields on this page

Layout controls in source order, grouped by the container they sit in. Shows: the table field a control is bound to (or its expression as written); ToolTip: the control's own, else the bound field's (marked).

| Group | Control | Shows | ToolTip |
|---|---|---|---|
| Group | Application Area | [Application Area](../table/9179.md#fields) | Specifies the scope of the application functionality for which fields and actions are shown. Fields and action for non-selected application areas are hidden to simplify the user interface. |
|  | Show in User Interface | [Selected](../table/9179.md#fields) | Specifies that fields and actions for the application area are shown in the user interface. |

## Procedures

1 local procedures, no public ones.

## Triggers

OnModifyRecord, OnOpenPage, OnQueryClosePage

## Relations

- source table [Table 9179 "Application Area Buffer"](../table/9179.md)

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 9178 "Application Area Mgmt."](../codeunit/9178.md) (2 calls: `OnOpenPage → GetApplicationAreaBuffer`, `TrySave → TrySaveApplicationAreaCurrentCompany`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: none

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "page", object_name: "Application Area")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
