Conditional format or another way.

Hi all, I'm still having trouble sorting out how to view changes on my spreadsheet.

I have a tab called SAP DUMP where we copy our raw data to, from here we manually copy and paste into another sheet called ORDER TRACKING SHEET. When we do a fresh dump (overwrite) of raw data into the SAP DUMP tap we need to see if the there is a new entry which needs to be copied across to the ORDER TRACKING SHEET. I've got a vlookup to show this. The one I can't work out is that on the ORDER TRACKING SHEET I also need to see if there are any entries are now no longer on the SAP DUMP tab. This is where I thought a condition format might work, color the line red if it's no longer on the SAP DUMP tap. Can't make it work.....

Thanks Dave

Hi all
Can someone please expand on how I would do this?
