Extends [No. Series](../page/456.md).

## Actions

| Group | Action | ToolTip | Runs |
|---|---|---|---|
| addfirst(Prompting) | Generate | Generate No. Series using Copilot |  |

## Triggers

OnOpenPage

## Relations

- extends [Page 456 "No. Series"](../page/456.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 324 "No. Series Copilot Impl."](../codeunit/324.md) (1 call: `OnOpenPage → IsCopilotVisible`)

## Across versions

- Present in: BC25-30
- 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: "pageextension", object_name: "No. Series Ext.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
