hello All,

add a new array/character to cm3r, map the field to new a table(a8 in my env).

click ok in dbdict.

when click SM alerts.

meet below errors:

An error occurred while attempting to update a record (record.update,start)

Additional errors have been written to the log. Contact your system administrator (record.update,start)
