Learn documents this table through its pages: [Page 5658 "Main Asset Components"](../page/5658.md) (1 Learn page).

## Properties

| Property | Value |
|---|---|
| Caption | Main Asset Component |
| DataClassification | CustomerContent |

## 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 |
|---|---|---|---|---|
| 1 | Main Asset No. | Code[20] | Specifies the number of the main asset. This is the asset for which components can be set up. | TableRelation [Table 5600 "Fixed Asset"](../table/5600.md) (Fixed Asset); not editable; NotBlank |
| 3 | FA No. | Code[20] | Specifies the number of the related fixed asset. | TableRelation [Table 5600 "Fixed Asset"](../table/5600.md) (Fixed Asset); NotBlank |
| 4 | Description | Text[100] | Specifies the description linked to the fixed asset for the fixed asset number you entered in FA No. field. |  |

## Keys

- Key1: Main Asset No., FA No. (clustered)
- Key2: FA No.

## Events published

- `OnBeforeOnDelete(var MainAssetComponent: Record "Main Asset Component"; var IsHandled: Boolean)` (integration)
- `OnBeforeValidateFANo(var MainAssetComponent: Record "Main Asset Component"; var IsHandled: Boolean)` (integration)

## Procedures

## Pages and codeunits on this table

- [Page 5658 "Main Asset Components"](../page/5658.md) (source table)

## 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 5616 "Depreciation Calculation"](../codeunit/5616.md) (1 call: `CreateError → FAName`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24, BC28

## Countries that replace it

[RU](../../localizations/ru.md)

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: "table", object_name: "Main Asset Component")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
