# Page 99000811 "Prod. BOM Where-Used"

> Page 99000811 "Prod. BOM Where-Used" in Base Application (Microsoft.Manufacturing.ProductionBOM). 4 public procedures, 3 events. Present since at least BC23, still in BC30.

Base Application · Microsoft.Manufacturing.ProductionBOM · BC23-30 · [source at ea08af5e](https://github.com/microsoft/BCApps/blob/ea08af5ef2d6a9b5c5af4a029288abbe2c883220/src/Layers/W1/BaseApp/Manufacturing/ProductionBOM/ProdBOMWhereUsed.Page.al) · facts from BC29

## Properties

| Property | Value |
|---|---|
| Caption | Prod. BOM Where-Used |
| SourceTable | Where-Used Line |
| PageType | Worksheet |

## Fields on this page

Layout controls in source order, grouped by the container they sit in. Shows: the table field a control is bound to (or its expression as written); ToolTip: the control's own, else the bound field's (marked).

| Group | Control | Shows | ToolTip |
|---|---|---|---|
| Options | Calculation Date | `CalculateDate` | Specifies the date for which you want to show the where-used lines. |
|  | Levels | `ShowLevel` | Specifies the level of detail for the where-used lines. |
| Control1 | Item No. | `Rec."Item No."` | — |
|  | Version Code | `Rec."Version Code"` | — |
|  | Description | `Rec.Description` | — |
|  | Quantity Needed | `Rec."Quantity Needed"` | — |

## Events published

- `OnAfterBuildForm(var WhereUsedManagement: Codeunit "Where-Used Management"; ShowLevel: Option; Item: Record Item; ProductionBOMHeader: Record "Production BOM Header"; CalculateDate: Date)` (integration)
- `OnBeforeBuildForm(var WhereUsedManagement: Codeunit "Where-Used Management"; ShowLevel: Option)` (integration)
- `OnBeforeSetCaption(Item: Record Item; ProdBOM: Record "Production BOM Header"; var Result: Text; var IsHandled: Boolean)` (integration)

## Procedures

- `SetProdBOM(NewProdBOMHeader: Record "Production BOM Header"; NewCalcDate: Date)`
- `SetItem(NewItem: Record Item; NewCalcDate: Date)`
- `BuildForm()`
- `SetCaption(): Text`

Plus 3 local procedures.

## Triggers

OnAfterGetRecord, OnFindRecord, OnNextRecord, OnOpenPage

## 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 99000770 "Where-Used Management"](../codeunit/99000770.md) (4 calls: `BuildForm → WhereUsedFromItem`, `BuildForm → WhereUsedFromProdBOM`, `OnFindRecord → FindRecord`, …)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: none

## Documented on Microsoft Learn

- [Create production BOMs](https://learn.microsoft.com/dynamics365/business-central/production-how-to-create-production-boms)

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: "page", object_name: "Prod. BOM Where-Used")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
