SA_HR 604 SP upgrade from base patch 00 to 01/02/patch

Hello,

I just upgraded SAP_HR from 600-45 to 604-00 ( base patch level) through SUM.

Now I am going to upgrade it to patch 01/02 through SPAM but when i click on display/define and select SAP_HR, it's showing no support packages for this selection. However SAP_HR is at 604 000 level. I also uncar SP SAPKE60401.SAR in EPS/in and uploaded them also.

It can be possible through SPAM or SUM only?

Please help me out.

Thanks,

Pavan
