Assuming that the sample is in A2:C10, add labels before the first
record, e.g., X, Y, and Z.

Apply Advanced Filter on A:B with the Unique records only option checked
such that:

X Y
111 168
112 168
113 169
120 170

appears in D1:E5.

In F2 enter & copy down:

=SUMPRODUCT(--($A$2:$A$10=D2),--($B$2:$B$10=E2),$C$2:$C$10)

This setup does not replace the original data if that's what you have in
mind.

2 kolonu advenced filter ile filtreliyom
fakat ikinci kolon filtrelenirken SUM yapılmasını istiyom
nasıl yaparım


abi çok sağol ama asıl problem

A B C
111 168 1.250
111 168 2.500
112 168 3.250
112 168 5.250
113 169 8.200
120 170 1000
120 170 3000
120 170 6000
120 170 4000

bunu aşağıdaki hale getircek
A B C
111 168 3.750
112 168 8.500
113 169 8.200
120 170 14000

[1] The SumProduct function should implicitly coerce the truth values to
their Excel numeric equivalents.
[2] The lookup functions should have an optional argument for the return
value, defaulting to #N/A in its absence.
