## 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 1410 "Doc. Exch. Service Mgt."](../codeunit/1410.md) (2 calls: `CheckAndUpdateDocExchCrMemoStatus → GetDocumentStatus`, `CheckAndUpdateDocExchInvoiceStatus → GetDocumentStatus`)

## Called by

- [Codeunit 1420 "Doc. Exch. Serv.- Doc. Status"](../codeunit/1420.md) (4 calls: `CheckAndUpdateDocExchStatus → CheckAndUpdateDocExchCrMemoStatus`, `CheckAndUpdateDocExchStatus → CheckAndUpdateDocExchInvoiceStatus`, `CheckPostedCrMemos → CheckAndUpdateDocExchCrMemoStatus`, …)
- [Codeunit 1410 "Doc. Exch. Service Mgt."](../codeunit/1410.md) (2 calls: `DispatchDocument → UpdateDocumentRecord`, `SendUBLDocument → UpdateDocumentRecord`)

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## 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: "Doc. Exch. Links")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
