Hi Jorge,
check these notes
813658 - Repairs for upgrades to products based on SAP NW 2004s AS
1299009 - Central Note: Upgrade Systems on SAP NetWeaver 7.0 EHP 2
The correction package is provided as SAR archive that you must integrate into the upgrade. Each SAR archive is valid for only one product (= exactly one delivered DVD set).
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 7.02 -> #OS independent
Unpack the SAR archive using "SAPCAR -xvf <name>. SAR" You will get two files, one of them is <Correction package name>.UPG, the other one contains a history of changes.
Regards
Prashanth
