Learn documents this table through its pages: [Page 1105 "Cost Allocation"](../page/1105.md) (2 Learn pages), [Page 1102 "Cost Allocation Sources"](../page/1102.md) (1).

## Properties

| Property | Value |
|---|---|
| Caption | Cost Allocation Source |
| 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 | ID | Code[10] | Specifies the ID that applies to the cost allocation. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> |  |
| 2 | Level | Integer | Specifies by which level the cost allocation posting is done. For example, this makes sure that costs are allocated at level 1 from the ADM cost center to the WORKSHOP and PROD cost centers, before they are allocated at level 2 from the PROD cost center to the FURNITURE, CHAIRS, and PAINT cost objec... <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> |  |
| 3 | Valid From | Date | Specifies the date when the cost allocation starts. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> |  |
| 4 | Valid To | Date | Specifies the date that the cost allocation ends. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> |  |
| 5 | Cost Type Range | Code[30] | Specifies a cost type range to define which cost types are allocated. If all costs that are incurred by the cost center are allocated, you do not have to set a cost type range. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> | TableRelation [Table 1103 "Cost Type"](../table/1103.md) (Cost Type) |
| 6 | Cost Center Code | Code[20] | Specifies the cost center code. The code serves as a default value for cost posting that is captured later in the cost journal. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> | TableRelation [Table 1112 "Cost Center"](../table/1112.md) (Cost Center) |
| 7 | Cost Object Code | Code[20] | Specifies the cost object code. The code serves as a default value for cost posting that is captured later in the cost journal. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> | TableRelation [Table 1113 "Cost Object"](../table/1113.md) (Cost Object) |
| 8 | Variant | Code[10] | Specifies the variant of the cost allocation. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> |  |
| 10 | Credit to Cost Type | Code[20] | Specifies the cost type to which the credit posting is posted. The costs that are allocated are credited to the source cost center. It is useful to set up a helping cost type to later identify the allocation postings in the statistics and reports. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> | TableRelation [Table 1103 "Cost Type"](../table/1103.md) (Cost Type) |
| 20 | Comment | Text[50] | Specifies a comment that applies to the cost allocation. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> |  |
| 22 | Total Share | Decimal | Specifies the sum of the shares allocated. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> | FlowField: sum("Cost Allocation Target".Share where(ID = field(ID))); not editable |
| 30 | Blocked | Boolean | Specifies that the related record is blocked from being posted in transactions, for example a customer that is declared insolvent or an item that is placed in quarantine. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> |  |
| 60 | Last Date Modified | Date | Specifies when the cost allocation was last modified. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> | not editable |
| 61 | User ID | Code[50] | Specifies the ID of the user who posted the entry, to be used, for example, in the change log. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> | TableRelation User."User Name"; not editable; DataClassification EndUserIdentifiableInformation |
| 100 | Allocation Source Type | Option | Specifies if the allocation comes from both budgeted and actual costs, only budgeted costs, or only actual costs. <small>via [Page 1105 "Cost Allocation"](../page/1105.md)</small> | OptionCaption: Both,Actual,Budget |

## Ask your agent

Procedure bodies are not stored here (D10). 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: "Cost Allocation Source")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
