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 66 "Purch - Calc Disc. By Type"](../codeunit/66.md) (2 calls: `OnRun → ResetRecalculateInvoiceDisc`, `OnRun → ShouldRedistributeInvoiceDiscountAmount`)
- [Codeunit 170 "Standard Codes Mgt."](../codeunit/170.md) (1 call: `CreatePurchHeader → SetSkipRecurringLines`)
- [Codeunit 441 "Prepayment Mgt."](../codeunit/441.md) (1 call: `OnRun → SetPurchPrepaymentPct`)
- [Codeunit 447 "Record Link Management"](../codeunit/447.md) (1 call: `OnRun → CopyLinks`)

## Countries that replace it

[IT](../../localizations/it.md)

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: "Blanket Purch. Order to Order")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
