## 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 1630 "Office Management"](../codeunit/1630.md) (18 calls: `CloseEnginePage → CloseCurrentPage`, `EmailHasAttachments → EmailHasAttachments`, `GetContext → GetTempOfficeAddinContext`, …)
- [Page 1173 "Document Attachment Details"](../page/1173.md) (1 call: `OnInit → EmailHasAttachments`)
- [Page 1178 "Doc. Attachment List Factbox"](../page/1178.md) (1 call: `OnInit → EmailHasAttachments`)

## Across versions

## 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: "Office Host Management")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
