Just an update:
I checked all those listed notes, they are already in my system. My system is already SAP_GWFND SP14. Those notes are for SP13.
But I found another note which Fixed the issue . 
2256525 - Incorrect internal length is calculated for properties
One good way I found to search for oss note is:
go to the SAP NOTE and KBA search tool, and type in your frontend or backend support package name, and it will list out all the oss notes. Going through them one by one, should be able to find the one you need.
