Scrolling in the past on the portal timesheet

Hi,

In configuration for the CATS data entry profiles (CAC1), there's an option to set a "Lower Limit relative" which prevents the user from scrolling back the amount of periods in this field if they use CAT2. If this value is set to "1", it prevents the employee from going back in the past more than 1 period.

Does this setting also work in the portal timesheet, as currently the user can scroll back as far as they want and make changes.

The client wants to prevent the user from changing time entries past one period.

Is there a way to do this, and can someone confirm whether the setting in CAC1 does not work in the portal.

THanks
