## Triggers

OnRun

## Relations

- runs on [Table 27 "Item"](../table/27.md)

## 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 99000854 "Inventory Profile Offsetting"](../codeunit/99000854.md) (7 calls: `CalculateAndGetPlanningCompList → CalculatePlanFromWorksheet`, `CalculateAndGetPlanningCompList → GetPlanningCompList`, `CalculateAndGetPlanningCompList → SetParm`, …)
- [Codeunit 99000845 "Reservation Management"](../codeunit/99000845.md) (2 calls: `Finalize → AutoTrack`, `Finalize → SetReservSource`)

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: "Calc. Item Plan - Plan Wksh.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
