CONCLUSION ----------- This issue arises due to the UNIQUE INDEX defined for the PK CONSTRAINT.
The issue is documented in the DataWarehousing Guide.
Chapter 16 Maintaining the Data Warehouse " If the partitioned table has a primary or unique key that is enforced with a global index structure, ensure that the constraint on sales_pk_jan01 is validated without the creation of an index structure, as in the following:
ALTER TABLE sales_01_2001 ADD CONSTRAINT sales_pk_jan01 PRIMARY KEY (sales_transaction_id) DISABLE VALIDATE;
The creation of the constraint with ENABLE clause would cause the creation of a unique index, which does not match a local index structure of the partitioned table. You must not have any index structure built on the nonpartitioned table to be exchanged for existing global indexes of the partitioned table. The exchange command would fail.

( note DISABLE VALIDATE and WITHOUT VALIDATION; are required) THIS WORKS |
