## 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 4037 "Helper Functions"](../codeunit/4037.md) (11 calls: `GetUnpostedBatchCounts → GetUnpostedBatchCountForCompany`, `RunCustomerValidation → CleanGPPhoneOrFaxNumber`, `RunCustomerValidation → ContainsAlphaChars`, …)

## 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: "GP Migration Validator")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
