## Properties

| Property | Value |
|---|---|
| Caption | 'attachments', Locked = true |
| Extensible | false |
| SourceTable | Attachment Entity Buffer |
| PageType | API |

## 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 | id | [Id](../table/5509.md#fields) | — |
|  | parentId | [Document Id](../table/5509.md#fields) | — |
|  | fileName | [File Name](../table/5509.md#fields) | Specifies the Description for the Item. |
|  | byteSize | [Byte Size](../table/5509.md#fields) | — |

## Procedures

1 local procedures, no public ones.

## Triggers

OnDeleteRecord, OnFindRecord, OnInsertRecord, OnModifyRecord

## Relations

- source table [Table 5509 "Attachment Entity Buffer"](../table/5509.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 5503 "Graph Mgt - Attachment Buffer"](../codeunit/5503.md) (7 calls: `ByteSizeFromContent → GetContentLength`, `OnDeleteRecord → PropagateDeleteAttachment`, `OnFindRecord → GetDocumentIdFromAttachmentId`, …)
- [Codeunit 4100 "Temp Blob"](../codeunit/4100.md) (1 call: `ByteSizeFromContent → FromRecord`)
- [Codeunit 419 "File Management"](../codeunit/419.md) (1 call: `OnInsertRecord → IsValidFileName`)

## Across versions

- Present in: BC29-30
- 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: "APIV1 - Attachments")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
