Dear Ireneusz,
please understand that such workaround - skipping the installation of a package - is not supported by SAP Support.
The log you mentioned had warnings only, not errors. The real problem can be seen here:
A2EE/CTSPLUG/CTS_PLG_MSG 051 tp "IMPND" call failed for trkorr "SUBSET", tp-RC " "
A2EE/CTSPLUG/CTS_PLG_MSG 051 tp "IMPND" call failed for trkorr "SUBSET", tp-RC " "
A2 E/CTSPLUG/CTS_PLG_MSG 052 tp return code "0", RFC message: &1"0"&2"Could not convert from 4103 codepage to 1100 codep"
1AETR012XProgram canceled (job "RDDEXECL", number "19202100")
1AEPU320 See job log"RDDEXECL""19202100""ER1"
You have to check the job RDDEXECL details in SM37 to find the work process it was run on; then you should go to ST11 and check the corresponding dev_w* file to find the root cause of this issue.
I'm posting this reply for the community to be aware that skipping errors during XPRAS - or any other upgrade phase - is not the solution.
Best regards,
Tomas Black
