## Procedures

- `GetModifiedSet(IntegrationTableMapping: Record "Integration Table Mapping"; TableFilter: Text; var SourceRecordRef: RecordRef): Boolean`: Opens SourceRecordRef on the source integration table for the given mapping and applies the supplied table filter. Returns true if at least one record matches.
- `GetBySystemId(IntegrationTableId: Integer; SystemId: Guid; var SourceRecordRef: RecordRef): Boolean`: Fetches a single source record from the given integration table by its SystemId into SourceRecordRef. Returns true if the record was found.
- `GetById(IntegrationTableMapping: Record "Integration Table Mapping"; ID: Variant; var SourceRecordRef: RecordRef): Boolean`: Fetches a single source integration-table record by its identifier into SourceRecordRef. The identifier is the integration UID field value - for Master Data Management the SystemId - passed as a Guid or its text form. A RecordId is environment-specific and only resolvable by the local same-environme...
- `GetByUidFilter(IntegrationTableMapping: Record "Integration Table Mapping"; UidFilter: Text; var SourceRecordRef: RecordRef): Boolean`: Opens the source integration table and returns the set of records whose integration UID field matches UidFilter (a filter expression, e.g. a list of SystemIds). Returns true if any matched.
- `GetByFilter(IntegrationTableMapping: Record "Integration Table Mapping"; TableFilter: Text; var SourceRecordRef: RecordRef): Boolean`: Opens SourceRecordRef on the source integration table and returns ALL records matching TableFilter (the whole set, not just those modified since the watermark) - used by coupling and uncoupling. Returns true if at least one record matches.

- Changed (declaration) in: none

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: "interface", object_name: "IMDM Data Source")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
