Clock In/ Out Corrections Application in ESS

Hello Experts,

I am configuring the Clock In/Out application for the employees. Just to test (as the application is still in DEV),

The employee's clock-in clock-out records are updated from the time recording terminal to Infotype 2011 via an interface. Now, when we try to use the SAP's clock-in clock-out corrections application to change the existing clock-in or clock-out time for any particular day, the application is not giving the date and time fields to change. However, when we create a new clock-in clock-out entry from ess, we are able to change the date and time for that entry but not for any entry that is transferred from the time recording terminal.

Any idea if the standard application can be used to change existing clock-in clock-out record or how can this scenario be met in ESS?

Please help me little bit urgent.

Thanks,

Punna.
