Hello Yi,
Yes, you can check in dev_icm (via ST11) or using SMICM (Goto -> Trace File -> Display All).
You should see something like:
"...
[Thr xxxx] HttpExtractArchive: extract archive X:\usr\sap\<SID>\DVEBMGS00\exe\ITS.SAR to X:/usr/sap/<SID>/DVEBMGS00/data/icmandir
SAPCAR: processing archive X:\usr\sap\<SID>\DVEBMGS00\exe\ITS.SAR (version 2.01)
...
SAPCAR: xxxxxx file(s) extracted
..."
Kind regards,
Cris
