Oracle Error Message
ORA-37105: (XSVPART05) Only variables dimensioned by a CONCAT PARTITION TEMPLATE can have string partitions.
Reason for the Error
User attempted to create an external partition on a partitioned variable, but the variable was dimensioned by a RANGE or LIST partition template.
Solution
Declare the partition INTERNAL instead of EXTERNAL, or use a CONCAT partition template in place of the RANGE or LIST partition template.
