Will 'Apply Actuals' service be not applicable for Resources with 'Uses Timesheet' disabled?

Hi All,

I would need help in understanding the 'Apply Actuals' Service in relevance to Resource's 'Uses Timesheet' Option..

Assuming Resource R1 is assigned with activities of Project P1...

Case 1:

R1's Timesheets have been Approved. P1's data date is set suitably & 'Apply Actuals' service is Run. It is also verified that R1's time/hours are reflecting against the corresponding Activity-Assignment. At a later point of time, R1's 'Uses Timesheet' is disabled. When this service is run, will the already applied R1's time/hours be lost?

Case 2:

R1's timesheets have been submitted & approved. R1's 'Uses Timesheet' is disabled. Now, P1's data date is appropriately set & the 'Apply Actuals' service is run. Will R1's time be applied?
