Hello Douglas,
regarding the ACT_UPG error, you can safely ignore it for EhP6 also, the same was as for EhP5.
Regarding the errors in XPRAS phase, the problem is, that some infoobjects of the BW technical content are inactive. If this is not a BW system, then the RSA1 has been started most probably sometime, which triggered the activation and check for those characteristics.
Please run the transaction RSTCO_ADMIN and use the "start installation" button to start the activation of those objects. Please note that the system must be changeable at this time.
In case the objects are still inactive, please use the report RSDG_IOBJ_ACTIVATE for the following characteristics:
0H_CHILDID
0H_NEXTID
0H_NODEID
0INFOPROV
0TCTMDXFC
0TCTMDXRT
Additionally please implement the note 1629923 and 1724314 and set the mentioned RSADMIN parameter to prevent the technical content installation during future upgrades.
If the objects are active, then no further activities will be needed.
Best regards,
Tomas Black
