In a CEEDAYS or CEESECS call, the value in the DD or DDD field was not valid for the given year and/or month. For example, MM/DD/YY with 02/29/90, or YYYY.DDD with 1990.366 are invalid because 1990 is not a leap year. This code can also be returned for any nonexistent date value such as June 31st or January 0.
The output value is set to 0.
Verify that the format of the input data matches the picture string specification and that input data contains a valid date.
