Hello guys

I think this one might be possible but I don't know the answer
I have a worksheet with 2 Sheets
Sheet1 will have records of items sent out for repair and Sheet2 will have records of unit returned repair but with a replacement serial number
In other words we sent out part# 123a and then a few days later we get a shippment with replacement units. The list will have the old and new serial number for reference.We also copy this list of the web for practical purpose
Anyway, The serial number in Sheet1 is in cell Column "E" and returned serial number in Sheet2 is in Column "H
I need to create a report or some sort of inventory on a 3rd sheet
Is there a way to compare serial numbers from sheet1 and sheet2 and then create a report of serial numbers that we have on hand
Any other idea

Thank you.
