I have table with Sales. All Sales divide between Men and Women. I need to find out who have the biggest count of sales, men or woman.
I have tried using Summarize and MAXX together, but sonething is wrong.
MAXX(SUMMARIZE(
'public Brand',
'public Brand'[Возрастная группа],
"Свод",
COUNT('public Brand'[Id]))

Answer 1

If I understand your requirement correct, you need a single output "Men" OR "Women" based on the count sales count/amount. For example, if there are total 10 count or row for Men and 12 for Women, you need Women as output from the measure. I prepared a very simple data set for example (Excel part in the image) to calculate the measure. You can see the final output in the red marked box.
Here below is the Measure Code-
For most number of sales number
Gender With Most Count =
VAR Gourp_by_gender_with_count =
SUMMARIZE(
Sales,
Sales[Gender],
"GenderCount", COUNT(Sales[Gender])
)
VAR max_count_among_gender_group =
MAXX (
TOPN(1,Gourp_by_gender_with_count,[GenderCount],DESC),
[Gender]
)
RETURN max_count_among_gender_group
For most number of sales amount
Gender With Most Sales Amount =
VAR Gourp_by_gender_with_amount =
SUMMARIZE(
Sales,
Sales[Gender],
"GenderWiseSales", SUM(Sales[Amount])
)
VAR max_amount_among_gender_group =
MAXX (
TOPN(1,Gourp_by_gender_with_amount,[GenderWiseSales],DESC),
[Gender]
)
RETURN max_amount_among_gender_group
