we found that structure /1CRMG0/CNBCCPSAP005 has empty data type for each of its component types. this causes error each time we try to activate the structure and we can't proceed the upgrade to 2007.
we try to maintain the component type, but we encounter message "Object can only be created in package of namespace /1CRMG0/". even we try to maintain in the suggested package, it prompts error System setting does not allow you to change R3TR TTYP /1CRMG0/CCPSAP005001T. we can't proceed further at this point.
we implemented sap note 0000817539 & 0000643510, but still no success.
any lead is really appreciated
