Dear Experts, I am a basis guy. Currently we are doing our system up grade project. ECC 6.0 to ECC 6.0 EHP 6. Also we update netwever , IS also. Currently we upgraded at development system. Now plan is quality. Before going to quality, we want to verify that all the components has been updated properly. Is there any thumb rule to check from BASIS Side? and there is nothing inconsistent component there. Can anybody help me on this ? Regards, Asaduzzaman
