Generic extractor using date as delta

Hi folks,

I have 2 questions that are related to Generic datasource having date as the delta specific field.

1. When INIT load is performed for this extractor, what is the start date it uses? there is no value in Safety Intervals so I would think it uses the current date only. If this is true, how do we get this extractor to start from, say start of the year? Or is this not possible with the INIT?

2. When FULL LOAD is performed on this extractor, does it append any criteria that is related to the date field on which delta has been enabled? or completely ignores it? Just looking for a confirmation.

THanks.
