Numeric overflows are handled differently depending on whether you are running ANSI or Teradata mode, and whether you are running in Field Mode or not.

Field Mode is not ANSI SQL:2011 compatible. In Field Mode, conversion to a numeric or decimal data type that results in a numeric overflow is returned as asterisks (‘***’) rather than an error message.

Record and Indicator Modes do not behave in this manner and return an error message.
