Hello everyone,
I have a dataset array with names,ranks and durations
[Name] [Rank] [Duration]
[xxxx ] [ MAS ] [6]
[xxxx] [MAS] [5]
[yyyy] [MAS] [5]
[yyyy] [MAS] [4]
[yyyy] [CO] [7]
[yyyy] [CO] [6]
xxxx 1st person
yyyy 2nd person
I want to calculate the sum of durations per name and per rank
1st person : 11 months as MAS
2nd person: 9 months as MAS and 13 months as CO
How can I achieve this?
