The object <object name> is already locked by <user name>. Do you want to reobtain the lock?
You tried to edit an object that has been locked by the user name. Either someone used the user name and password to access this object, or the client shut down while you were working on the object.
If someone is using the user name and password, click No, then ask that person to close the object and log out. If the PowerCenter Client shut down while you were working on the object, and you are sure that no one else has the object open, click Yes.
Choosing Yes when someone else is working on the object may cause permanent damage to the repository.
