ways to extract the delta records in to the SAP-BW from MS Sequel Server Tables.

Hi Experts,

I need to extract the data from the tables of MS Sequel Server in to the SAP-BW on daily basis with DB connect.

As we have huge records we can not go with the full update mode and I need to implement the delta mechanism to extract the records on daily basis in to the SAP-BW.

For your information : @ MS Sequel server in table contains one field : " Changed Date & Time ".

MS Sequel server team suggesting to extract the delta records based on the Changed Date & Time field. 

Now Can you suggest me the ways to extract the delta records in to the SAP-BW.

Thanks,

Suresh.
