## Triggers

OnRun

## Relations

- runs on [Table 5830 "Availability Calc. Overview"](../table/5830.md)

## Called by

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.

- [Page 5830 "Demand Overview"](../page/5830.md) (6 calls: `ExpandAll → CalculateDate`, `ExpandAll → CalculateItem`, `ExpandAll → EntriesExist`, …)

- [Codeunit 99000874 "Assembly Availability Mgt."](../codeunit/99000874.md) (4 calls: `OnGetDemandDates → InsertAvailabilityEntry`, `OnGetDemandEntries → InsertAvailabilityEntry`, `OnGetSupplyDates → InsertAvailabilityEntry`, …)

## 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: "Calc. Availability Overview")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
