The table name prefix is the owner of the target table. For some databases, such as DB2, tables can have different owners. If the database user specified in the database connection is not the owner of the target tables in a session, specify the table owner for each target instance. A session can fail if the database user is not the owner and you do not specify the table owner name.

You can specify the table owner name in the target instance or on the Mapping tab of the session properties. When you specify the table owner name in the session properties, you override table owner name in the transformation properties.

You can use a parameter or variable as the target table name prefix. Use any parameter or variable type that you can define in the parameter file. For example, you can use a session parameter, $ParamMyPrefix, as the table name prefix, and set $ParamMyPrefix to the table name prefix in the parameter file.
