Base Application · Microsoft.Assembly.Document · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/Assembly/Document/ReleaseAssemblyDocument.Codeunit.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| TableNo | Assembly Header |
| Permissions | TableData "Assembly Header" = rm, TableData "Assembly Line" = r |

## Events published

- `OnAfterReleaseAssemblyDoc(var AssemblyHeader: Record "Assembly Header")` (integration)
- `OnAfterReopenAssemblyDoc(var AssemblyHeader: Record "Assembly Header")` (integration)
- `OnBeforeReleaseAssemblyDoc(var AssemblyHeader: Record "Assembly Header")` (integration)
- `OnBeforeReopenAssemblyDoc(var AssemblyHeader: Record "Assembly Header")` (integration)

## Procedures

- `Reopen(var AssemblyHeader: Record "Assembly Header")`

## 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 904 "Whse.-Assembly Release"](../codeunit/904.md) (2 calls: `OnRun → Release`, `Reopen → Reopen`)

## Called by

- [Codeunit 414 "Release Sales Document"](../codeunit/414.md) (2 calls: `ReleaseATOs → (object)`, `ReopenATOs → Reopen`)
- [Codeunit 900 "Assembly-Post"](../codeunit/900.md) (1 call: `InitPost → (object)`)
- [Table 900 "Assembly Header"](../table/900.md) (1 call: `PerformManualRelease → (object)`)
- [Table 904 "Assemble-to-Order Link"](../table/904.md) (1 call: `AsmReopenIfReleased → Reopen`)

## 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: "codeunit", object_name: "Release Assembly Document")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
