Hi Divyanshu,
I found the note for the file 'FIX_NW730.UPG' the below.
SAP Note 1403832 - Central Note: Upgrade Systems on SAP NetWeaver 7.3
Part C: Correction Package for the Upgrade Program
The SAR archives are available at the following SAP Service Marketplace area:
http://service.sap.com/patches -> Browse our Download Catalog -> Additional Components -> Upgrade Tools -> CORRECTIONS FOR UPGRADE -> CORRECTIONS FOR UPGRADE 7.30-> #OS independent
There is one package for ABAP and Java:
Package Name: FIX_NW730.UPG
But, i don't find the file FIX_NW730.UPG in SAP Marketplace.
