I am curious as to how you came up with this chron command?
Looking at chron, there are 5 fields, you have 16. Also date >> /tmp/mycron.log; /usr/bin/perl /share/script/Test/report.pl seems suspect as that is not the normal command line syntax for redirection. What is "date"? /usr/bin/perl /share/script/Test/report.pl >> /tmp/mycron.log would seem more logical to me.
