Space Bar does not display previous entered values in sap screens?

Hi Experts,

the Space bar does not displaying the previous entered values. I have checked the Options->Local data->History Status and it is switched ON and also it is set for the High Speed connection(LAN).

But still i am not getting the SPACE BAR help in SAP Screens!

Please help me on this issue.

Thanks
