Duplicates and unique values
 

hi,
I have the data as follow:
Month Employee IC Department
Jan Tom 123 HR
Feb Tom 123 HR
Mar Tom 123 IT

Expected result: Same department but different month is a duplicate. Same
person but NEW department is NOT a duplicate.
Month Employee IC Department Duplicates
(marked with 'x')
Jan Tom 123 HR
Feb Tom 123 HR x
Mar Tom 123 IT


To check for duplicates, I did... =IF(COUNTIF(C$2:C20,C20)1,"x","") where
column C is the unique IC number. How do i make sure that my guy in a new
department is not treated as a duplicate because the current function will
result in all but only one to be duplicates.

Duplicates and unique values
 

try this

Assumed Col A - Month
Col B - Employee
Col C - IC
Col D - Dept
Col E - Duplicate

in cell E2 put this formula and drag it down

=IF(COUNTIF($B$2:$B$10,B2)1,IF(COUNTIF($D$2:$D$10 ,D2)1,"X",""),"")
