Lock Serial

Explanation

This activity is used to lock a serial and its belonging structure. When a serial is locked, you cannot perform any changes to the serial in the system, except for the completion of running maintenance events. You can view information on locked serials. Following is a list of operations that cannot be performed on a serial that is locked:

Changes of serial data (includes vehicle data if the serial is a vehicle)
Changes in the serial structure (complete structure is locked)
Changes for serial transportation routes
Operational logging for a structure containing locked serials
Registration of faults (both serial and vehicle)
Condition measures
Due calculation for interval maintenance
Assigning to modifications
Definitions of start values
Planning of operational events
Distribution of pending events

Prerequisites

The serial must be a top serial (i.e., not have a connected parent). If the serial is connected to a parent, the serial has to be removed from the parents structure before you can lock the serial.
The serial must have an operational status of either In Operation or Out Of Operation.

System Effects

All serials in the entire structure are locked. Depending on which window or tab is opened, the Locked or Locked for Update check box will be selected.
You cannot perform any changes to the serial record other than for completing any running events.
Serials that are locked will not be assigned to modifications. The serials that are not locked will be assigned to modifications.
