## 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 419 "File Management"](../codeunit/419.md) (3 calls: `CreateSchemaConnection → GetFileName`, `ExtractXMLSchema → IsAllowedPath`, `ExtractXMLSchema → ServerTempFileName`)
- [Codeunit 4100 "Temp Blob"](../codeunit/4100.md) (2 calls: `CreateBook → CreateInStream`, `OpenBook → CreateInStream`)

## Called by

- [Codeunit 8618 "Config. Excel Exchange"](../codeunit/8618.md) (14 calls: `AddAndInitializeTableDefinitionPart → AppendAutoFilter`, `AddAndInitializeTableDefinitionPart → AppendTableStyleInfo`, `AddAndInitializeTableDefinitionPart → GetXLColumnID`, …)
- [Codeunit 8610 "Questionnaire Management"](../codeunit/8610.md) (8 calls: `AddColumns → AddColumnHeaderWithXPath`, `ExportQuestionnaireToExcel → AddTable`, `ExportQuestionnaireToExcel → CleanMapInfo`, …)
- [Table 370 "Excel Buffer"](../table/370.md) (5 calls: `CreateBook → SetupWorksheetHelper`, `UpdateBookExcel → SetupWorksheetHelper`, `WriteCellValueInternal → CreateCommentVmlShapeXml`, …)

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