ORA-14295: column type or size mismatch between partitioning columns and subpartitioning columns

What triggered the Error:

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

What should we do to fix it:

Ensure that the type and size of the partitioning columns of the partitioned is the same as the type and size of the subpartitioning columns of the composite partition.
