## Properties

| Property | Value |
|---|---|
| TableNo | Job Planning Line |

## Events published

- `OnBeforeOnRun(var JobPlanningLine: Record "Job Planning Line"; var IsHandled: Boolean)` (integration)

## Procedures

- `CallExplodeBOMCompLines(JobPlanningLine: Record "Job Planning Line")`

Plus 12 local procedures.

## Triggers

OnRun

## Relations

- runs on [Table 1003 "Job Planning Line"](../table/1003.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 5402 "Unit of Measure Management"](../codeunit/5402.md) (5 calls: `AssingJobPlannigLineDataFromBOMComp → GetQtyPerUnitOfMeasure`, `ValidateQtyAndUoMForDifferentTypes → GetQtyPerUnitOfMeasure`, `ValidateQtyAndUoMForDifferentTypes → GetQtyRoundingPrecision`, …)
- [Codeunit 378 "Transfer Extended Text"](../codeunit/378.md) (4 calls: `AddExtText → InsertJobExtText`, `AddExtText → JobCheckIfAnyExtText`, `ExplodeBOMCompLines → InsertJobExtText`, …)
- [Codeunit 99000845 "Reservation Management"](../codeunit/99000845.md) (3 calls: `DeleteReservEntries → DeleteReservEntries`, `DeleteReservEntries → SetItemTrackingHandling`, `DeleteReservEntries → SetReservSource`)

## Called by

- [Page 1007 "Job Planning Lines"](../page/1007.md) (1 call: `ExplodeBOM → (object)`)
- [Page 1015 "Job Planning Lines Part"](../page/1015.md) (1 call: `ExplodeBOM → (object)`)

## Across versions

- Present in: BC24-30
- Changed (declaration) in: BC26

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: "Job-Explode BOM")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
