## Properties

| Property | Value |
|---|---|
| Caption | Cost Budget per Period Matrix |
| SourceTable | Cost Type |
| PageType | ListPart |

## 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 |
|---|---|---|---|
| Control12 | No. | [No.](../table/1103.md#fields) | Specifies the number of the involved entry or record, according to the specified number series. |
|  | Name | [Name](../table/1103.md#fields) | Specifies the name of the cost type. |
|  | Column1 | `MATRIX_CellData[1]` | — |
|  | Column2 | `MATRIX_CellData[2]` | — |
|  | Column3 | `MATRIX_CellData[3]` | — |
|  | Column4 | `MATRIX_CellData[4]` | — |
|  | Column5 | `MATRIX_CellData[5]` | — |
|  | Column6 | `MATRIX_CellData[6]` | — |
|  | Column7 | `MATRIX_CellData[7]` | — |
|  | Column8 | `MATRIX_CellData[8]` | — |
|  | Column9 | `MATRIX_CellData[9]` | — |
|  | Column10 | `MATRIX_CellData[10]` | — |

## Actions

| Group | Action | ToolTip | Runs |
|---|---|---|---|
| Cost Type | Card | View or edit detailed information for the cost type. | [Page 1101 "Cost Type Card"](../page/1101.md) |
|  | Entries | View the entries for the cost budget per period. | [Page 1103 "Cost Entries"](../page/1103.md) |
| Functions | Copy Cost Budget to Cost Budget | Copy cost budget amounts within a budget or from budget to budget. You can copy a budget several times and enter a factor to increase or reduce the budget amounts. |  |
|  | Copy G/L Budget to Cost Budget | — | [Report 1135 "Copy G/L Budget to Cost Acctg."](../report/1135.md) |
|  | Copy Cost Budget to G/L Budget | Copy selected cost budget entries into the general ledger. Multiplication factors and multiple copies with date offsets are also possible. |  |
|  | Compress Budget Entries | Compresses cost budget entries so that they take up less space in the database. |  |

## Relations

- source table [Table 1103 "Cost Type"](../table/1103.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 9200 "Matrix Management"](../codeunit/9200.md) (2 calls: `LoadMatrix → FormatRoundingFactor`, `MATRIX_OnAfterGetRecord → RoundAmount`)

## Recent changes

- 2026-08-04 [#9545 636017 Move Cost Accounting report action tooltips to report objects](../../changes/bcapps/9545.md) (main, BC30, refactor)

## Across versions

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

## Documented on Microsoft Learn

- [Creating cost budgets](https://learn.microsoft.com/dynamics365/business-central/finance-create-cost-budgets)

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: "Cost Budget per Period Matrix")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
