Where are the change objects that are associated with a change notice located in ORACLE?

I am trying to find the WT parts associated with a change notice in the Oracle database.

I created a change notice and 1 task (1 record each in WTChangeOrder/Master and WTChangeActivity/Master). There are 2 WTPart records that are linked to this task. In what table(s) are these stored? I have looked in STRUCTUREDANNOTATIONSET and SUPPORTINGDATAFOR but the records are not there. (one table has no records whatsoever; the other has none modified in the last 2 months.)
