Invalid specification message noting issue with charater data length when specifying system defau (4229155)

When trying to create or alter a table Toad gives the message:

"Invalid Specification - When specifying a system default value of SESSION USER, the datatype column for column CRETD_BY_ID must support character data with a minimum length of 128. "

or

Table script sample:

CREATE TABLE "DUMMY" (
  "DUMMY_ID" INTEGER NOT NULL GENERATED BY DEFAULT
    AS IDENTITY (START WITH 1, INCREMENT BY 1, CACHE 20,
       NO MINVALUE, NO MAXVALUE, NO CYCLE, NO ORDER),
  "CRETD_BY_ID" VARCHAR(8) DEFAULT USER,
  "CRETD_BY_TS" TIMESTAMP DEFAULT ,
  "MDFYD_BY_ID" VARCHAR(8),
  "MDFYD_BY_TS" TIMESTAMP
)

This error on any version of DB2...8.2, 9.5, 9.7 etc.  on Toad for DB2. Changes on newer versions of DB2 require character data length of minimum 128.

WORKAROUND:

Alter the table/column to length 128 or more.
