Extends [BOM Buffer](../table/5870.md).

## Fields

Explanation: the field's ToolTip in the code; without one, the ToolTip of a page control bound to the field (marked via the page); without that, its Caption (marked caption) when that differs from the name.

| No. | Name | Type | Explanation | Notes |
|---|---|---|---|---|
| 15 | Routing No. | Code[20] | Specifies the number of the item's production order routing. <small>via [Page extension 99000757 "Mfg. BOM Cost Shares"](../pageextension/99000757.md)</small> | TableRelation [Table 99000763 "Routing Header"](../table/99000763.md) (Routing Header); DataClassification SystemMetadata |
| 16 | Production BOM No. | Code[20] | Specifies the number of the production BOM that the item represents. <small>via [Page extension 99000757 "Mfg. BOM Cost Shares"](../pageextension/99000757.md)</small> | TableRelation [Table 99000771 "Production BOM Header"](../table/99000771.md) (Production BOM Header); DataClassification SystemMetadata |

## 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) (2 calls: `TransferFromProdComp → GetQtyPerUnitOfMeasure`, `TransferFromProdComp → QtyRndPrecision`)
- [Codeunit 99000758 "Mfg. Cost Calculation Mgt."](../codeunit/99000758.md) (2 calls: `TransferFromProdComp → CalcCompItemQtyBase`, `TransferFromProdComp → CalcQtyAdjdForBOMScrap`)
- [Codeunit 99000755 "Shop Calendar Management"](../codeunit/99000755.md) (1 call: `CalcQtyPerParentFromProdRouting → TimeFactor`)

## Across versions

- Present in: BC27-30
- Changed (declaration) in: none

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: "tableextension", object_name: "Mfg. BOM Buffer")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
