Hi,

You need to implement a routine of Authorizing the time reporting, once a month has passed. Once a day (or a certain period) is Authorized, it is no longer possible to register any new time reporting on that date/period. It is not possible to delete or modify any existing records either. Thus, by Authorizing a month, you close/block that period for any changes.

But what if no time reporting has been done on that period ? we have this case where employees report time too late  - after we closed the month, but on account dates on the past, it is possible to prevent this ? 

​@Zineb : You can create a custom event/ custom event action to prevent time reporting, if period is closed. Enter condition (e.g. current date - 30 days) till how many days, past time reporting should be blocked. When user try to enter the time reporting for past dates, then custom event action will show the error message.

Thanks
