# Codeunit 7783 "AOAI User Message"

> Codeunit 7783 "AOAI User Message" in System Application (System.AI). 6 public procedures. Introduced in BC28, still in BC30.

System Application · System.AI · BC28-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/System%20Application/App/AI/src/Azure%20OpenAI/Chat%20Completion/AOAIUserMessage.Codeunit.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| Access | Public |

## Procedures

- `AddTextPart(TextContent: Text)`
- `AddFilePart(FileData: Text)`
- `GetContentParts(): JsonArray` (internal): Gets the assembled content parts as a JsonArray.
- `IsSet(): Boolean` (internal): Get if the User Message has been set.
- `HasFilePart(): Boolean` (internal): Get if the user message contains file part. This is used to determine if the message is compatible with the deployment model, as some models do not support file content.
- `HasTextPart(): Boolean` (internal): Get if the user message contains text part.

## 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 7784 "AOAI User Message Impl"](../codeunit/7784.md) (7 calls: `AddFilePart → AddFilePart`, `AddTextPart → AddTextPart`, `GetContentParts → GetContentParts`, …)

## Called by

- [Codeunit 7764 "AOAI Chat Messages Impl"](../codeunit/7764.md) (3 calls: `CheckCompatibilityWithModel → HasFilePart`, `PrepareHistory → GetContentParts`, `PrepareHistory → IsSet`)
- [Codeunit 4421 "SOA Attachment MLLM"](../codeunit/4421.md) (2 calls: `TryExtractAttachmentContent → AddFilePart`, `TryExtractAttachmentContent → AddTextPart`)

## Recent changes

- 2026-08-28 [#10680 Maintenance update](../../changes/bcapps/10680.md) (main, BC30, fix)

## Across versions

- Present in: BC28-30
- 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: "AOAI User Message")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
