## Properties

| Property | Value |
|---|---|
| TableNo | Assembly Header |

## Event subscriptions

- OnRunPreview subscribes to Codeunit "Gen. Jnl.-Post Preview" OnRunPreview

- `MessageIfPostingPreviewMultipleDocuments(var AssemblyHeaderToPreview: Record "Assembly Header"; DocumentNo: Code[20])`

Plus 1 local procedures.

## Triggers

OnRun

## Relations

- runs on [Table 900 "Assembly Header"](../table/900.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 900 "Assembly-Post"](../codeunit/900.md) (4 calls: `Code → (object)`, `OnRunPreview → (object)`, `OnRunPreview → SetPreviewMode`, …)
- [Codeunit 19 "Gen. Jnl.-Post Preview"](../codeunit/19.md) (2 calls: `MessageIfPostingPreviewMultipleDocuments → MessageIfPostingPreviewMultipleDocuments`, `Preview → Preview`)

## Called by

- [Page 902 "Assembly Orders"](../page/902.md) (2 calls: `ShowPreview → MessageIfPostingPreviewMultipleDocuments`, `ShowPreview → Preview`)
- [Page 900 "Assembly Order"](../page/900.md) (1 call: `ShowPreview → Preview`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24

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: "codeunit", object_name: "Assembly-Post (Yes/No)")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
