Comparing and mark data from two different worksheet

Hello guys. I'm new and i wanna ask experts here how to solve my problem.


I have two worksheet and each contains series of Serial Number and Operation Number. So how can the first worksheet ( will be marked) can be compared with the second worksheet ( reference ) if it has the same Serial Number and Operation number ( fullfill both conditions) . If the first worksheet contains redundant data, the third row will be marked and indicated, let say with "submitted" .

I have read about vlookup and if function, but i'm not doing so well or maybe they doesnt suit this kind of problem .


Thanks in advance for helping.
