Hi all,

I have a data table with one data column having numbers stored.

c0 c1 c2

a 1 /

a 1 /

b 2 /

b 2 /

a 3 /

I would like to have a “x” set in column c2 set, when the value in c1 is available twice in the entire data table and only when in c0 is an “a”.

Result:

c0 c1 c2

a 1 x

a 1 x

b 2 /

b 2 /

a 3 /

Can you please help me out with that?

Thank you and kr,

GrKa
