"ITEM_NUMBER" VARCHAR2(81 BYTE),

"COST_TYPE" VARCHAR2(50 BYTE),

"COST_ELEMENT" VARCHAR2(50 BYTE),

"USAGE_RATE_OR_AMOUNT" VARCHAR2(50 BYTE)

   ORGANIZATION EXTERNAL

    ( TYPE ORACLE_LOADER

      DEFAULT DIRECTORY "XX_DEST_DIR"

      ACCESS PARAMETERS

      ( RECORDS DELIMITED BY NEWLINE

                    FIELDS TERMINATED BY ","

                  MISSING FIELD VALUES ARE NULL    )

      LOCATION

       ( 'No Cost HMLK PN_Org 7_20140915_145226.csv'

   REJECT LIMIT UNLIMITED ;
