Hi Jitendra,
your SAP release has to be on EHP6 level. Then you are able to upgrade just Finbasis and its dependend components. Otherwise you have to perform an upgrade to EHP6.
Please check note #1326576 in that case.
If your SAP release is already EHP6, but just Finbasis component is 600 level then you have to configure a valid stackfile according to above note and use this one while patching your system.
Cheers,
Andreas
