## Properties

| Property | Value |
|---|---|
| Caption | Data Migration Status |
| 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 |

## Keys

- [Page 1799 "Data Migration Overview"](../page/1799.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 1798 "Data Migration Mgt."](../codeunit/1798.md) (1 call: `OnModify → CheckIfMigrationIsCompleted`)

## Across versions

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

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: "Data Migration Status")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
