Thank you for your post into the Data Compare for Oracle.
Data Compare for Oracle recognises the "t-Address" table in the source to be a different table to the "Address" table in the target and does not map them.
Sadly, unlike our SQL Data Compare, Data Compare for Oracle does not have a Table Mapping feature where you could manually map the "t-Address" table in the source to the "Address" table in the target. Therefore I have added the details of this forum post to an existing Feature Request to compare tables of different names. The reference number for this Feature Request is ODC-179. Hopefully this feature will appear in a future version of the Data Compare for Oracle product.
