Thanks Srivats,
Our first focus is whatever the ticket are correct should update. If the some ticket have some issue, it should not stop other ticket to save.
If we can achieve this then we can track all erroneous ticket, because those ticket have not been updated.
(I don't know among 5000 ticket which ticket are erroneous and what attribute of ticket is wrong, so I cant stop these in code)

Sunil
