# Codeunit 30 "Error Context Element"

> Codeunit 30 "Error Context Element" in Base Application (System.Utilities). 5 public procedures, 3 event subscribers. Present since at least BC23, still in BC30.

Base Application · System.Utilities · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/Modules/System/ErrorMessage/ErrorContextElement.Codeunit.al) · facts from BC29

## Event subscriptions

- OnGetTopElementDataHandler subscribes to Codeunit "Error Message Management" OnGetTopElementData
- OnGetTopElementHandler subscribes to Codeunit "Error Message Management" OnGetTopElement
- OnGetTopContextHandler subscribes to Codeunit "Error Message Management" OnGetTopContext

## Procedures

- `GetID(): Integer`
- `Set(ID: Integer; ContextRecID: RecordID; ContextFldNo: Integer; AdditionalInfo: Text[250])`
- `GetData(var ID: Integer; var ContextRecID: RecordID; var ContextFldNo: Integer; var AdditionalInfo: Text[250])`
- `Copy(ErrorContextElement: Codeunit "Error Context Element")`
- `GetErrorMessage(var ErrorMessage: Record "Error Message")`

## Triggers

OnRun

## Called by

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 28 "Error Message Management"](../codeunit/28.md) (2 calls: `PushContext → GetID`, `PushContext → Set`)
- [Codeunit 31 "Last Error Context Element"](../codeunit/31.md) (2 calls: `GetErrorMessage → GetErrorMessage`, `Set → Copy`)

## 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: "Error Context Element")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
