Use the UPDATE LOCK option to assign a lock level to restrict access to an occurrence. You can use one level to restrict updates to an occurrence and another level to restrict both updates and display of the occurrence. CA Datacom Datadictionary provides the following three levels of lock instructions:
Applies no maintenance restrictions to an occurrence.
Restricts an occurrence from updates or deletion unless the override code is specified at the time the function request is issued. You can copy, display, or print an occurrence with a LOCK1 assignment without specifying the override code.
Restricts any action to the occurrence unless you specify the override code in the function request. This restriction includes copying, updating, deleting, displaying, or printing the occurrence.
Do not update lock levels for occurrences maintained by other CA products unless specifically documented by the product.
