Hi Taro,
I am using IHC as my origin.
I have tested my configuration in another version 606 11 i.e. EHP6 (SBX) and this problem does not exists in EHP6.
However, my QAS and PRD are still on EHP5 60511.
It appears there is a sap note that corrected this from 605 11 to 606 11.
I have logged a call with SAP and still awaiting their feedback.
Any other ideas are welcome.
Thanks & Regards,
Godhelp
