Lock/Unlock Functionality

Throughout the system there are built-in features that help prevent data from being duplicated by blocking multiple users from editing/updating the same records at the same time. Windows, data, and procedures that have been set in motion can be locked to other users as a means of protecting the integrity of said records. This functionality helps keep track of components, authorizations, and work floor duties.

For instance, if two users are trying to edit the same Repair Order record at the same time, the user who accessed the Repair Order after the first user will not be allowed to edit the record. This only happens if the very same record is selected at the same time.

Many of these locks can be unlocked by supervisors by selecting the Unlock button for that particular record. See below list for more information.

The following are the main examples of this functionality in the system.

The following information/options are available in this window:

A/C Hold

Upon placing an A/C on Hold, via A/C Registration Change, if multiple users are attempting to conduct this action, the following users will be prevented from repeating the action with the "In Use" hard warning.

Manual Issue button (Inventory Transaction)

Once a serialized part has been manually issued from inventory to a W/O or Aircraft, that part cannot be reserved for any other W/O. Once the batch is issued, the status for that serialized part in Inventory Transaction becomes Pending Technical Records. This status indicates, for example, that the part must either be installed onto an aircraft or Returned to Stock (RTS) manually before being available for use in Inventory. While in this status, when the Manual Issue button is selected in the Inventory Transaction window, a warning prevents users from proceeding. For more information refer to the Manual Issue Button via the Inventory Training Manual.

When the Picklist is marked as 'In Use', the user who has the Picklist locked will be listed to the right of the checkbox. The Unlock Picklist button from the Informational tab is also available when the Picklist is in use. These features are also available in the Picklist Supervisor, Informational tab.
