Please how do I get expired_flag to show either 0 for current or 1 for expired rows? I am migrating data from a table that has Position_Start_Date and Position_End_Date which I mapped to my new fields called Effective_Date and Expired_Date respectively in the destination table. I also do have a field on my destination table called Expired_Flag. I am having a hard time getting this field to either show 0 if the record is expired or 1 if not. How do I make use of the fields position_start_date and position_end_date to cause the expired_flag to respond accordingly?
