## Procedures

- `ApplyRetentionPolicyAllRecordFilters(RetentionPolicySetup: Record "Retention Policy Setup"; var FilterRecordRef: RecordRef; var RetenPolFilteringParam: Record "Reten. Pol. Filtering Param" temporary): Boolean`
- `ApplyRetentionPolicySubSetFilters(RetentionPolicySetup: Record "Retention Policy Setup"; var FilterRecordRef: RecordRef; var RetenPolFilteringParam: Record "Reten. Pol. Filtering Param" temporary): Boolean`: This method is called when the retention policy defines subsets of records. The records in FilterRecordRef must be marked to indicate they are part of the union of all subsets.
- `HasReadPermission(TableId: Integer): Boolean`: This method is used to determine whether the implementation has read permission to the table specified in TableId. The permissions depend on both the user and the implementation codeunit. If the combination of user and implementation codeunit do not have read permission to the table, the retention p...
- `Count(RecordRef: RecordRef): Integer`: This method is to count the records in the table specified in the RecRef. The method is only called when the base code does not have read permission to the table.

## Across versions

- Present in: BC23-30
- 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). 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: "Reten. Pol. Filtering")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
