Hi, Farhad

Thanks for your reply!
The formula does work but the values in E column are being returned to Flag
clolumn instead of the Flag values. Plus, by using FALSE as the range_lookup
value, once the data does not matched; an error message will be returned
instead of No values from Flag column in File A.
is there any other functions can help to solve these?

Thanks!

in this case an extra column will help you to use vlookup as follow:

file A
A B C D E
1 Brand Type Unit Flag extra column
2 AA 123 2 Yes =A1&B1&C1
3 AB 234 No
4 No

file B
A B C D E
Brand Type Unit Flag
1 AA 123 2 =vlookup(E1,fileA!E1:E?,1,false) =A1&B1&C1
2 AB 234 3
3 CC 135 5


Hope it works

hi,

I have 2 files, Files A (old) contained data in below order:-
Brand Type Unit Flag
AA 123 2 Yes
AB 234 No
No

In File B, data are organized in below order:-
Brand Type Unit Flag
AA 123 2

AB 234 3
CC 135 5

What I would like to know is how to compare each value in Brand, Type & Unit
whether they are the same in each file; if they are the same then the Flag
value in File A will be returned; else No will be retruned in File B.

Actually, I have tried out using Vlookup functions but unfortunately, this
function can only compare data in 1 column. So, is there any other functions
that can help in solving this problem?

Thanking in advanced.
