## Referenced by

1 fields in 1 objects relate to this table (TableRelation or CalcFormula).

- [Table 1799 "Data Migration Status"](../table/1799.md): Error Count

## Pages and codeunits on this table

## Extended by

- [Table extension 46898 "BC14 Data Migration Error Ext"](../tableextension/46898.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 1796 "Data Migration Error Logging"](../codeunit/1796.md) (2 calls: `UpdateErrorLogging → GetFullListOfLastRecordsUnderProcessingAsText`, `UpdateErrorLogging → GetLastRecordUnderProcessing`)
- [Codeunit 6101 "Data Migration Status Facade"](../codeunit/6101.md) (1 call: `Ignore → IgnoreErrors`)

## Across versions

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

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