You can define the owner name of the source table in the session properties. 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 source tables in a session, specify the table owner for each source instance. A session can fail if the database user is not the owner and you do not specify the table owner name.
You can use a parameter or variable as the table owner name. Use any parameter or variable type that you can define in the parameter file. For example, you can use a session parameter, $ParamMyTableOwner, as the table owner name, and set $ParamMyTableOwner to the table owner name in the parameter file. Use a mapping parameter to include the owner name with the table name in the following types of overrides: source filter, user-defined join, query override, or pre- or post-SQL.
