Validation

DTE fields are automatically validated by CA 2E. Dates are automatically translated from external to internal format and vice-versa. Dates are validated to be in the external format when entered on a panel and converted to internal format when written to a file.

A date cannot be converted if its day, month, or year portion has an out-of-range value. If you enter an invalid date, the message, "Invalid date" is issued and the date is redisplayed in reverse image according to the output edit code:

• If the edit code has a four-digit-year format (YYYY), the invalid day and month portions are reproduced as they were entered. An invalid year is replaced by the special value 9999 to indicate that the entered year is out of range.
• If the edit code has a two-digit-year format (YY), all date portions are reproduced with no change.

Examples of DTE fields include:

• Date of birth
• Order date
• Creation date
