## 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) (17 calls: `ExportAttachmentToClientFile → DeleteServerFile`, `ExportAttachmentToClientFile → Magicpath`, `ExportAttachmentToClientFile → ServerTempFileName`, …)
- [Codeunit 4100 "Temp Blob"](../codeunit/4100.md) (4 calls: `ExportAttachmentToServerFile → FromRecord`, `ExportAttachmentToTempBlob → FromRecord`, `ProcessWebAttachment → FromRecord`, …)
- [Codeunit 5052 "AttachmentManagement"](../codeunit/5052.md) (2 calls: `ImportAttachmentFromClientFile → InsertAttachment`, `PreviewHTMLContent → LoadHTMLContent`)
- [Codeunit 5069 "Word Template Interactions"](../codeunit/5069.md) (2 calls: `ShowAttachment → IsWordDocumentExtension`, `ShowAttachment → RunMergedDocument`)
- [Codeunit 9500 "Sequence No. Mgt."](../codeunit/9500.md) (2 calls: `InsertRecord → GetNextSeqNo`, `InsertRecord → RebaseSeqNo`)
- [Codeunit 4030 "Client Type Management"](../codeunit/4030.md) (1 call: `OpenAttachment → GetCurrentClientType`)

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