When saving Auto Filing Rule for My eB folder error message received. Error: The Folder 'My eB' is controlled by the System - you may not modify it. If you were attempting to assign the 'Modify' permission to the object instance this might be the cause, this permission is not applicable to this instance.
In eB version 16 type of My eB folder has changed and some actions/functionalities were lost regarding implemented changes. This has been raised internally as bug (functionality loss)
Auto Filing Rule works fine on all other type folders. As a workaround, sub folder under My eB should be created and Auto Filing Rule added to suborder, instead of directly on My eB.
