UNIQUE constraints mismatch in ALTER TABLE EXCHANGE PARTITION

One of the tables named in the ALTER TABLE EXCHANGE PARTITION command has a UNIQUE constraint for which no matching (vis-a-vis key columns) constraint is defined on the other table or a matching constraint is defined on the other table, but it differs from that defined on the first table vis-a-vis being enabled and/or validated.

How to Solve :

Ensure that for every UNIQUE constraint defined on one of the tables named in the ALTER TABLE EXCHANGE PARTITION statement there is a matching (vis-a-vis key columns and being enabled and/or validated) UNIQUE constraint defined on the other table. If UNIQUE constrains are enabled, UNIQUE constraints on the partitioned table should be enforced using local indexes.
