can't edit cron solaris 10

This morning, there is a problem with the cron service misuse of one production server. Initial plan to edit the crontab file for user applications, but strange when doing cron-e that the contents of the file does not exist and can not add and insert the command in cron.

1. Check list file crontab
user_aplication@localhost # crontab -l
0 23 * * * /u02/applprod/backup_daily.sh
09 06 * * * /u02/applprod/backup_daily_up.sh

2. Try add and insert command
user_aplication@localhost # crontab -e
0

86
? [

(press ctrl+d, exit from editor cron)
user_aplication@localhost #

3. Check service cron
user_aplication@localhost # svcs cron
STATE STIME FMRI
online 9:08:01 svc:/system/cron:default

4. Solving problem,
a. edit file crontab
user_aplication@localhost # vi /var/spool/cron/crontabs/user_aplication
0 23 * * * /u02/applprod/backup_daily.sh > /dev/null 2>&1
09 06 * * * /u02/applprod/backup_daily_up.sh > /dev/null 2>&1

:wq!

b. refresh daemon cron
user_aplication@localhost # svcadm disable svc:/system/cron:default
user_aplication@localhost # svcadm enable svc:/system/cron:default

5. done
