## 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 6233 "Sust. Preview Post Instance"](../codeunit/6233.md) (3 calls: `OnAfterFillDocumentEntry → InsertDocumentEntry`, `OnAfterShowEntries → ShowEntries`, `OnAfterShowEntries → ShowSustValueEntries`)
- [Page 6220 "Sustainability Ledger Entries"](../page/6220.md) (1 call: `OnBeforeShowRecords → (object)`)
- [Page 6248 "Sustainability Value Entries"](../page/6248.md) (1 call: `OnBeforeShowRecords → (object)`)

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: "Sust. Preview Post. Subscriber")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
