## 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 6700 "O365 Sync. Management"](../codeunit/6700.md) (5 calls: `LogFailure → LogActivityFailed`, `LogFailure → TraceCategory`, `ProcessNavContactRecordSet → LogActivityFailed`, …)
- [Codeunit 8613 "Config. Try Validate"](../codeunit/8613.md) (2 calls: `TryValidateField → (object)`, `TryValidateField → SetValidateParameters`)

## 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: "O365 Contact Sync. Helper")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
