## Procedures

6 local procedures, no public ones.

## Calls

From the extracted call graph of BC30 (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 5431 "Calc. Item Plan - Plan Wksh."](../codeunit/5431.md) (5 calls: `OnSimulatePlanningOnRunCalcItemPlan → (object)`, `OnSimulatePlanningOnRunCalcItemPlan → Initialize`, `OnSimulatePlanningOnRunCalcItemPlan → SetParm`, …)
- [Codeunit 700 "Page Management"](../codeunit/700.md) (1 call: `OnShowDocumentOnElseCase → GetPageID`)
- [Codeunit 99000756 "VersionManagement"](../codeunit/99000756.md) (1 call: `ShouldTrackThisBom → GetBOMVersion`)

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC30 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: "Mfg. Supply What-If Plan. Eng.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
