Necessary steps for a daily delta load

Expert Jay Narayanan assists a user who wants to start peforming daily delta loads.

What are the steps that should be taken for a delta load? I am trying to do an "init without data transfer". I was doing "full loads" of till data up until the previous month and now I am starting with delta loads. Eventually I want to include daily delta loads in the process chain. Will you help me?
If you are planning to do delta loads without data transfer, you will have to make sure that the full load and delta loads are in sync. This means there is a possibility that you will load duplicate records or even miss some of the records if not preformed properly. The best way to do this is to do all the full loads up to the current day at a quiet time, and then do the delta init.
