In V10.3 and later, logic in ctsqlimp checks for the maximum number of indexes or segments. When importing tables, this logic checks if the number of indexes defined is less than MAX_DAT_KEY value and the number of segments per key is less than MAX_KEY_SEG value. The new logic prevents the import unless you are using interactive ctsqlimp, which asks if you want to continue with the import because it may be useful to import the table and adjust the server setting afterwards.
