Update Rules Problem

Hello,

I have created ODS with 4 fields (1 Key,3 Data). I am populating it from a flat file and the requirements that even if the 2 data fields have changed their values I should populate it from the initial values of data fields. In other way, for every new record I have to insert values, for every updated record I need to use the previous one.

Please guide if anyone has faced the same issue.

Thanks
