Calculate all equal values (sales for a group)

[Stever25]

Hello,

thank you for helping with my little Problem. I have customer and some customers together forms a group. It easy to calculate sales for each custumer with a measure or a calculated coloum.  How can I calculate the sales for the whole group (group sales)?.

cust. nr.	group	solo sales	group sales
10	A	10	40
11	A	10	40
12	A	10	40
13	B	10	30
14	B	10	30
15	A	10	40
16	C	10	10
17	B	10	30

Try, 

If you are adding a column then:

sum(table[solo])

for Meaure,
calculate ( sum(table[solo]) , all(table[group]))
