Thanks Ashish,
Unfortunately, I would not be able to upgrade to SP10 in the near future. We're planning to go to SP09 next month. I will check it out when that happened and report back.
One of the consultant in our project mentioned that SAP_UI SP10 does not compatible with SAP_BW SP8, which does not makes any sense to me. This is the reason why I got push back to have SAP_UI SP10. Have you heard any such incompatibility issue?
