You can use overrides to void the lock protection. Setting the system-level override nullifies all locks, and setting a group-level override nullifies all the locks below that group.
Open the Advanced Option dialog box at one of the following levels:
System level--select Option->Advanced from the Menu bar.
Group level--place your pointer over the group and right-click. Then select Test Advanced Options.
Enable the Override setting (or disable the Override setting to unset it).
Click Apply.
