Run load_status_script.sql during incremental load

Hi,

As I understand we run load_status_script.sql on source system as part of FTI Installation/Configuration process. I would like to know how do we take care of "HD_LOAD_STATUS" and "READY_TO_LOAD" for Status_type_GID and Status_Value_Gid
while performing Incremental load.
How do we change value of these column's once new data is entered?

Thanks
Sasn
