## 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 5404 "Lead-Time Management"](../codeunit/5404.md) (3 calls: `CalcEarliestDueDate → GetPlannedDueDate`, `CalcEarliestDueDate → GetPlannedEndingDate`, `CalcEarliestDueDate → ManufacturingLeadTime`)
- [Codeunit 1511 "Notification Lifecycle Mgt."](../codeunit/1511.md) (2 calls: `CreateAndSendNotification → RecallNotificationsForRecordWithAdditionalContext`, `CreateAndSendNotification → SendNotificationWithAdditionalContext`)
- [Codeunit 311 "Item-Check Avail."](../codeunit/311.md) (2 calls: `ShowAssemblyAvailability → AsmOrderCalculate`, `UpdateAssemblyLines → RaiseUpdateInterruptedError`)
- [Codeunit 6500 "Item Tracking Management"](../codeunit/6500.md) (2 calls: `CreateWhseItemTrkgForAsmLines → GetWhseItemTrkgSetup`, `CreateWhseItemTrkgForAsmLines → InitItemTrackingForTempWhseWorksheetLine`)

## Called by

- [Table 900 "Assembly Header"](../table/900.md) (14 calls: `AddBOMLine → AddBOMLine`, `CompletelyPicked → CompletelyPicked`, `CreatePick → CreateWhseItemTrkgForAsmLines`, …)

## 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: "Assembly Line Management")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
