Spanish language pack is not working in SRM

Hello,

We have recently installed spanish language pack in SRM 7.0 with help of basis team. After installation, i see few fields are not translated to spanish and i see those in english when logged in with spanish language in SRM. Those are standard fields. For example, F4 help for cost center field under account assignment tab. We have re-imported language pack but still it is not working. Kindly share your idea/solution.

Regards,

Prasad
