## Events published

- `OnGetCheckDelayInMinutes(var DelayInMinutes: Integer)` (integration): Used for test. Sets the minimum age of stale job queue entries and job queue log entries.
- `OnRunJobQueueEntryOnceOnAfterJobQueueEntryInsert(SelectedJobQueueEntry: Record "Job Queue Entry"; JobQueueEntry: Record "Job Queue Entry")` (integration)
- `OnFindStaleJobsAndSetErrorOnAfterSetError(var JobQueueEntry: Record "Job Queue Entry")` (integration)

## Event subscriptions

- ScheduleReport subscribes to Codeunit "Reporting Triggers" ScheduleReport
- OnStatusChanged subscribes to Table "Job Queue Entry" OnAfterModifyEvent
- OnBeforeDeleteJobQueueEntry subscribes to Table "Job Queue Entry" OnBeforeDeleteEvent
- OnBeforeDeleteJobQueueLogEntry subscribes to Table "Job Queue Log Entry" OnBeforeDeleteEvent

## Procedures

- `CheckUserInJobQueueAdminList(UserName: Text): Boolean` (internal)
- `CreateJobQueueEntry(var JobQueueEntry: Record "Job Queue Entry")`
- `DeleteJobQueueEntries(ObjectTypeToDelete: Option; ObjectIdToDelete: Integer)`
- `StartInactiveJobQueueEntries(ObjectTypeToStart: Option; ObjectIdToStart: Integer)`

- `SetRecurringJobsOnHold(CompanyName: Text)`
- `SetStatusToOnHoldIfInstanceInactiveFor(PeriodType: Option Day,Week,Month,Quarter,Year; NoOfPeriods: Integer; ObjectTypeToSetOnHold: Option; ObjectIdToSetOnHold: Integer): Boolean`
- `RunJobQueueEntryOnce(var SelectedJobQueueEntry: Record "Job Queue Entry")`
- `CheckAndRefreshCategoryRecoveryTasks()`
- `FindStaleJobsAndSetError()`: To find stale jobs (in process jobs with no scheduled tasks) and set them to error state. For both JQE and JQLE
- `UpdateRetriableFailedJobQueueLogEntry(var JobQueueEntry: Record "Job Queue Entry")` (internal)
- `TooManyScheduledTasksNotification()` (internal)
- `GetScheduledTasks(): Integer` (internal)
- `GetScheduledTasksForUser(UserId: Guid): Integer` (internal)
- `TooManyScheduledTasksDocs(ScheduledTaskNotification: Notification)` (internal)

Plus 10 local procedures.

## 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: "Job Queue Management")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
