Upgrade of Clarity PPM 15.6 to 15.7 failing with the following error:
ERROR 18-11 22:47:19,990 - Error occured trying to materialize object "taskdependency"
com.niku.union.odf.exception.ODFException: Derived attributes supported only through a parent reference at this point. Either the parent object "task" does not exist or the derived through attribute "odf_parent_id" is not the parent reference attribute.
Release : 15.6
Component : CLARITY PPM
This issue is resolved after deleting a corrupt custom object id 'taskdependency'
