Ok someone once helped me with this but i've clean forgotten how to do it because it's quite technical.
I need to group data based on Member ID, by the latest date. This creates a list of Unique Member IDs. But in order to do this, I need to remove the Index else it won't focus just on grouping Member ID. But then once I've done this, I want the Index associated with the saved rows, to come back.
How do I do this?
