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 53 “Translation Helper” (8 calls: OnAfterDeleteChangeLogSetupField → RestoreGlobalLanguage, OnAfterDeleteChangeLogSetupField → SetGlobalLanguageToDefault, OnAfterInsertChangeLogSetupField → RestoreGlobalLanguage, …)
• Codeunit 1367 “Monitor Sensitive Field Data” (4 calls: GetDatabaseTableTriggerSetup → CheckIfTableIsMonitored, InsertLogEntry → HandleMonitorSensitiveFields, InsertLogEntry → IsIgnoredMonitorField, …)
• Codeunit 8711 “Telemetry” (4 calls: OnAfterDeleteChangeLogSetupField → LogMessage, OnAfterInsertChangeLogSetupField → LogMessage, OnAfterModifyChangeLogSetupField → LogMessage, …)

Called by

• Codeunit 49 “GlobalTriggerManagement” (5 calls: GetDatabaseTableTriggerSetup → GetDatabaseTableTriggerSetup, OnDatabaseDelete → LogDeletion, OnDatabaseInsert → LogInsertion, …)
• Table 405 “Change Log Entry” (1 call: GetLocalValue → EvaluateTextToFieldRef)

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: "Change Log Management"), then bcatlas_get_procedure_body or bcatlas_get_neighbors on the returned id.
