Change pointer for CRM data using MDM tool

Hi,

I am using the MDM tool for extracting data from CRM system to XI system. its successfully extracting records for initial load, now i am trying for the delta changes (Change pointers) where, i am not able to find the way for it.

I followed as per instruction downloaded , i gone to transaction BUPA_IFC_CALL_FU and created new lines BUPA_CREATE_CHANGE_POINTER and BUPR_CREATE_CHANGE_POINTER and activated the same. But while i am executing for delta changes in MDM_CLNT_EXTR is not transferring any changed data to XI.

Note : i am transferring all standard fields only , no custom field and using standard extraction function module.

Please guide me if any other thing i have missed on this,

Regards,

K.Sudhakaran.
