## 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 1173 "Document Attachment Mgmt"](../codeunit/1173.md) (8 calls: `FindUniqueFileName → IsDuplicateFile`, `InitFieldsFromRecRef → TableHasDocTypePrimaryKey`, `InitFieldsFromRecRef → TableHasLineNumberPrimaryKey`, …)
- [Codeunit 419 "File Management"](../codeunit/419.md) (6 calls: `Export → BLOBExport`, `InsertAttachment → GetExtension`, `InsertAttachment → GetFileNameWithoutExtension`, …)
- [Codeunit 4100 "Temp Blob"](../codeunit/4100.md) (5 calls: `DownloadZipFileWithVATReturnAttachments → CreateInStream`, `DownloadZipFileWithVATReturnAttachments → CreateOutStream`, `Export → CreateOutStream`, …)
- [Codeunit 425 "Data Compression"](../codeunit/425.md) (4 calls: `DownloadZipFileWithVATReturnAttachments → AddEntry`, `DownloadZipFileWithVATReturnAttachments → CloseZipArchive`, `DownloadZipFileWithVATReturnAttachments → CreateZipArchive`, …)
- [Codeunit 9510 "Document Service Management"](../codeunit/9510.md) (3 calls: `OpenInOneDrive → EditInOneDriveFromMedia`, `OpenInOneDrive → OpenInOneDriveFromMedia`, `OpenInOneDrive → ShareWithOneDriveFromMedia`)

## 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: "table", object_name: "Document Attachment")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
