ORA-14293: Number of partitioning columns does not match number of subpartitioning columns

What triggered the Error:

When exchanging a partitioned table with a composite partition the number of partitioning columns of the table must match the number of subpartitioning columns of the composite partition.

What should we do to fix it:

Ensure that the number of partitioning columns in the partitioned table is the same as the number of subpartitioning columns in the the composite partition.
