## Properties

| Property | Value |
|---|---|
| Caption | Merge Duplicates Buffer |
| DataClassification | CustomerContent |
| Permissions | tabledata "Sales Shipment Header" = rm |

## 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 | Table ID | Integer | — |  |
| 2 | Duplicate | Code[20] | — | TableRelation [Table 18 "Customer"](../table/18.md), [Table 23 "Vendor"](../table/23.md), [Table 5050 "Contact"](../table/5050.md) (if ("Table ID" = const(18)) Customer else if ("Table ID" = const(23)) Vendor else if ("Table ID" = const(5050)) Contact) |
| 3 | Current | Code[20] | — | TableRelation [Table 18 "Customer"](../table/18.md) (if ("Table ID" = const(18)) Customer) |
| 4 | Table Name | Text[30] | — | not editable |
| 5 | Conflicts | Integer | — |  |
| 6 | Duplicate Record ID | RecordID | — |  |
| 7 | Current Record ID | RecordID | — |  |
| 8 | Conflict Field ID | Integer | — |  |

## Pages and codeunits on this table

- [Page 702 "Merge Duplicate"](../page/702.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 27 "Confirm Management"](../codeunit/27.md) (3 calls: `Merge → GetResponseOrDefault`, `RemoveConflictingRecord → GetResponseOrDefault`, `RenameConflictingRecord → GetResponseOrDefault`)
- [Codeunit 408 "DimensionManagement"](../codeunit/408.md) (1 call: `IncludeDefaultDimTable → DefaultDimObjectNoList`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24-25

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: "Merge Duplicates Buffer")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
