I'm trying to manage hundreds of dates. The reason for snapshot is so that if the one date gets changes, I'll still have record of the original date no matter how many times its been changed. Unfortunately, you can't pull lookup field from the same table. So instead, I have tried to create relationship of the table with itself so I can have that lookup field but that didn't work out. What I want is the first time Construction Date is filled, so does the Original Construction Date. When Construction Date got pushed down, even a few times, the Original Construction Date will stay the same. Can anyone help me out?
