Server processing for the copy group command command fails because the value (retention value) specified for the RETEXTRA parameter is not valid.
Database changes for the command are rolled back and server operation continues. The command is not successful in changing the server database.
Reissue the command and specify a valid RETEXTRA value. For valid RETEXTRA values for the DEFINE COPYGROUP or UPDATE COPYGROUP commands, refer to the Administrator’s Reference for your particular platform.
