Sandeep,

TClientDatasets do not properly handle TLargeInts. The main problem comes
from the TParser that CDS uses internally for parsing things like FindKey
and Locate.

The best option is to use a memory-based dataset such as kbmMemDataset from
www.components4developers.com Kim Madsen is the developer and made it an
open source component. Works real well and accomplishes much of what CDS
will do and DOES handle LargeInts properly.
