If I am an Oracle Argus Safety Japan user, can I apply both a local and a global lock on a Local PRPT case that I entered?

Yes, you can apply both a local and a global lock on a Local PRPT case in one step if you select the Perform Local lock additionally for a Local PRPT case option in the Case Locking dialog box.

If this option isn't available, contact your Administrator to set the value for Enable Local Unlocking to Yes for your tenant.
