WI121: Can't import data file filename into table tablename because data file has number columns but table has number columns.

The source file and the target table in your Import operation do not have the same number of fields. If you are running a batch import, verify that the TABLE statement in the IMP file is set to the correct target table. Also verify that the FIELDS, TYPES, NULL_PERM, SRC_LENS, OFFSETS, USE_PIC and EBCDIC_TO_ASCII statements in your IMP file reflect the actual number of columns in your source and destination. See your SQLWizard User's Guide for a complete description of the IMP file and its contents.
