Symptoms
Domain constraints are not being propagated in the script created by an RMU/EXTRACT.
RMU/EXTRACT/ITEM=(tables)/OPTIONS=(nodomains)/LANG=ANSI does not take the default and/or validation of domains and propagate it to every column used by the domain.

or SUBSTRING(value from 1 for 1) between 'A' and 'Z'))
