# Codeunit 7249 "MDM Cross-Env Data Source"

> Codeunit 7249 "MDM Cross-Env Data Source" in MasterDataManagement (Microsoft.Integration.MDM). 9 public procedures, 1 events. Introduced in BC29, still in BC30.

## Properties

| Property | Value |
|---|---|
| Access | Internal |

## Events published

- `OnGetCrossEnvPageSize(var PageSize: Integer)` (internal)

## Procedures

- `GetModifiedSet(IntegrationTableMapping: Record "Integration Table Mapping"; TableFilter: Text; var SourceRecordRef: RecordRef): Boolean`
- `GetByFilter(IntegrationTableMapping: Record "Integration Table Mapping"; TableFilter: Text; var SourceRecordRef: RecordRef): Boolean`
- `GetModifiedBatch(IntegrationTableMapping: Record "Integration Table Mapping"; TableFilter: Text; StartCursor: Text; MaxPages: Integer; var SourceRecordRef: RecordRef; var EndCursor: Text; var HasMore: Boolean): Boolean` (internal): Fetches at most MaxPages pages of changed source records starting from StartCursor (a cursor selector). MaxPages = 0 means unbounded. On return EndCursor holds the resume point and HasMore tells the caller whether more pages remain past the cap, so the next job run can continue from where this one s...
- `SourceHasRecords(IntegrationTableMapping: Record "Integration Table Mapping"; TableFilter: Text): Boolean` (internal): Cheap existence probe for the full-synch review: the source reports an empty lastModifiedAt for an empty table, so this avoids counting the whole table over the wire.
- `GetBySystemId(IntegrationTableId: Integer; SystemId: Guid; var SourceRecordRef: RecordRef): Boolean`
- `GetById(IntegrationTableMapping: Record "Integration Table Mapping"; ID: Variant; var SourceRecordRef: RecordRef): Boolean`
- `GetByUidFilter(IntegrationTableMapping: Record "Integration Table Mapping"; UidFilter: Text; var SourceRecordRef: RecordRef): Boolean`
- `GetSourceRecordsByFilter(TableId: Integer; RowFilter: Text; var SourceRecordRef: RecordRef): Boolean` (internal)
- `TryBulkGetSourceRecordsByFilter(TableId: Integer; RowFilter: Text; var SourceRecordRef: RecordRef; var NotIndexed: Boolean): Boolean` (internal)

Plus 25 local procedures.

## 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.

## 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: "codeunit", object_name: "MDM Cross-Env Data Source")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
