## 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 827 "Service Post Invoice Events"](../codeunit/827.md) (25 calls: `CalcInvoiceDiscountPosting → RunOnBeforeCalcInvoiceDiscountPosting`, `CalcLineDiscountPosting → RunOnBeforeCalcLineDiscountPosting`, `GetSalesAccount → RunOnAfterGetSalesAccount`, …)
- [Codeunit 12 "Gen. Jnl.-Post Line"](../codeunit/12.md) (3 calls: `PostBalancingEntry → RunWithCheck`, `PostLedgerEntry → RunWithCheck`, `PostLines → RunWithCheck`)

## Implements

- [Interface "Invoice Posting"](../interface/invoice-posting.md)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC25-26

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: "Service Post Invoice")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
