Hi Santosh,
Ideally if the resource is enabled for Time Entry, timesheets for all the weeks should be showing in OPEN status.
You mentioned "1st and 2nd week timesheets were visible. Is this correct and as per functionality" and then also said that "All the 4 week timesheets were created and they are open". So this is a bit confusing. What is the exact problem now? Could you please clarify.
Thanks,
Abhisek Dhar
