## 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 5790 "Available to Promise"](../codeunit/5790.md) (5 calls: `CalcAvailableQty → CalcQtyAvailableToPromise`, `CalcAvailableQty → GetPeriodEndingDate`, `CalcAvailableQty → SetPromisingReqShipDate`, …)
- [Codeunit 5402 "Unit of Measure Management"](../codeunit/5402.md) (1 call: `InsertPromisingLine → QtyRndPrecision`)

## Called by

- [Codeunit 6452 "Serv. Availability Mgt."](../codeunit/6452.md) (2 calls: `OnOpenPageOnSetSource → SetSourceRecord`, `SetServiceHeader → InsertPromisingLine`)
- [Codeunit 99000871 "Job Planning Availability Mgt."](../codeunit/99000871.md) (2 calls: `OnOpenPageOnSetSource → SetSourceRecord`, `SetJob → InsertPromisingLine`)
- [Codeunit 99000872 "Sales Availability Mgt."](../codeunit/99000872.md) (2 calls: `OnOpenPageOnSetSource → SetSourceRecord`, `SetSalesHeader → InsertPromisingLine`)
- [Page 99000959 "Order Promising Lines"](../page/99000959.md) (1 call: `OnClosePage → CancelReservations`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC25, BC27-28

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: "AvailabilityManagement")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
