You cannot copy a source-controlled object to a destination PBL in the same directory as the source PBL. Generally when you work with source control, objects with the same name should not exist in more than one PBL in the same directory.
Moving an object that is not under source control to a destination PBL having a source-controlled object with the same name is permitted only when the second object is checked out of source control.
You cannot move an object from a source PBL if the object is under source control, even when the object has been checked out. The right way to move an object under source control is described below.
To move an object under source control from one PBL to another:
Export the object from the first PBL.
Remove the object from source control.
Delete the object from the first PBL.
Import the object into the second PBL.
Register the object in source control once again.
