WebI and Rich client report inconsistency

I've created a report which runs perfectly well on "Web Intelligence Desktop Rich Client" albeit when I try to run on BI Launch Pad using browser its generating " Database Error: [Microsoft].................. could not be prepared..[IES 10901]" . However surprisingly I can view script (from Data Access > Edit  >View Script 'SQL) on WebI followed by execute successfully in SQL Server 2008.

Only when I run/refresh the report generate this error below -

Any quick advise ?

FYI

- Universe works fine - I ran the integrity check result is "OK", Universe object name is clearly defined. Plus can able to generate SQL from universe. (*.unv).

- Web Intelligence Desktop Rich Client Version 14.0.7

- Web Intelligence Version 14.0.7

- Universe Design Tool ( UDT) Version 14.0.7

Cheers,
