## Properties

| Property | Value |
|---|---|
| Caption | Cost Element Buffer |
| 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 | Type | Enum "Cost Entry Type" | — | enum [Enum 104 "Cost Entry Type"](../enum/104.md); DataClassification SystemMetadata |
| 2 | Variance Type | Enum "Cost Variance Type" | — | enum [Enum 106 "Cost Variance Type"](../enum/106.md); DataClassification SystemMetadata |
| 3 | Actual Cost | Decimal | — | DataClassification SystemMetadata |
| 4 | Actual Cost (ACY) | Decimal | — | DataClassification SystemMetadata |
| 5 | Rounding Residual | Decimal | — | DataClassification SystemMetadata |
| 6 | Rounding Residual (ACY) | Decimal | — | DataClassification SystemMetadata |
| 7 | Expected Cost | Decimal | — | DataClassification SystemMetadata |
| 8 | Expected Cost (ACY) | Decimal | — | DataClassification SystemMetadata |
| 9 | Invoiced Quantity | Decimal | — | DataClassification SystemMetadata |
| 10 | Remaining Quantity | Decimal | — | DataClassification SystemMetadata |
| 11 | Inbound Completely Invoiced | Boolean | — | DataClassification SystemMetadata |
| 12 | Last Valid Value Entry No | Integer | — | DataClassification SystemMetadata |

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). 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 Element Buffer")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
