Cause . . . . . : If the first parameter of built-in function %TIMESTAMP is of type character or numeric, the second operand must be a valid timestamp format. If the first parameter of built-in function %TIMESTAMP is *SYS, or is of type date or timestamp, or numeric, the second operand must be a numeric constant with zero decimal positions between 0 and 12 representing the number of fractional seconds in the timestamp. The second parameter is ignored.
Recovery . . . : Correct the second parameter for the built-in function. Compile again.
