## Triggers

OnRun

## Relations

- runs on [Table 3901 "Retention Policy Setup"](../table/3901.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 3908 "Retention Policy Log"](../codeunit/3908.md) (15 calls: `ApplyRetentionPolicy → LogInfo`, `CanApplyRetentionPolicy → LogError`, `ConfirmApplyRetentionPolicies → LogError`, …)
- [Codeunit 3905 "Reten. Pol. Allowed Tables"](../codeunit/3905.md) (3 calls: `CanApplyRetentionPolicy → IsAllowedTable`, `DeleteExpiredRecords → GetRetenPolDeleting`, `GetExpiredRecords → GetRetenPolFiltering`)
- [Codeunit 3910 "Apply Retention Policy"](../codeunit/3910.md) (3 calls: `DeleteExpiredRecords → OnApplyRetentionPolicyIndirectPermissionRequired`, `RaiseRecordLimitExceededEvent → OnApplyRetentionPolicyRecordLimitExceeded`, `TruncateTableRecords → OnTruncateRecordsIndirectPermissionRequired`)
- [Codeunit 152 "User Permissions"](../codeunit/152.md) (2 calls: `TruncateTableRecords → GetEffectivePermission`, `VerifyIndirectDeletePermission → GetEffectivePermission`)
- [Codeunit 3906 "Reten. Pol. Allowed Tbl. Impl."](../codeunit/3906.md) (1 call: `TruncateTableRecords → IsTruncateAllowed`)
- [Codeunit 3912 "Reten. Policy Telemetry Impl."](../codeunit/3912.md) (1 call: `DeleteExpiredRecords → SendTelemetryOnRecordsDeleted`)
- [Codeunit 3917 "Record Reference"](../codeunit/3917.md) (1 call: `GetExpiredRecords → Initialize`)
- [Codeunit 8703 "Feature Telemetry"](../codeunit/8703.md) (1 call: `TruncateTableRecords → LogUsage`)

## Called by

- [Codeunit 3910 "Apply Retention Policy"](../codeunit/3910.md) (7 calls: `ApplyRetentionPolicy → ApplyRetentionPolicy`, `GetExpiredRecordCount → GetExpiredRecordCount`, `OnRun → (object)`, …)
- [Codeunit 3915 "Reten. Pol. Filtering Impl."](../codeunit/3915.md) (1 call: `ApplyRetentionPolicySubSetFilters → MaxNumberOfRecordsToDelete`)
- [Codeunit 3916 "Reten. Pol. Delete. Impl."](../codeunit/3916.md) (1 call: `NumberOfRecordsToDeleteBuffer → NumberOfRecordsToDeleteBuffer`)

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: "codeunit", object_name: "Apply Retention Policy Impl.")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
