The following is the ORA-14523 error message, you can learn the cause and solution of the Oracle database error.

ORA-14523 Cannot co-locate [sub]partition of string string with table [sub]partition because string block size [string] does not match table block size [string]

Cause: A DDL statement was issued that would require a partition/subpartition of a local index/LOB column to be co-located with the corresponding partition/subpartition of the base table. However, this is not possible because the block sizes of the table and the LOB column/local index are different.

Solution: Either (1) Specify an object-level default tablespace (or partition-level default tablespace for the appropriate partition, if composite partitioning is used) for the partitioned local index/LOB column and then retry the DDL command, OR (2) Ensure that tablespaces of the correct block size are specified for all new partitions/subpartitions being created. Also ensure that neither of TABLESPACE DEFAULT and STORE IN (DEFAULT) is specified for a local index whose block size does not match that of the base table.
