what are required fields you're talking here? Is it like each month only deltas (new changes) or you want entire data to be replicated at the end of each month?you can use the below logic for get data filtered for current month...WHERE yourdatefield >= DATEADD(mm,DATEDIFF(mm,0,GETDATE()),0)AND yourdatefield < DATEADD(mm,DATEDIFF(mm,0,GETDATE())+1,0)
