I would like when i select one month to have the values of Unique Customers.
When a user selects a quarter (Q1, Q2, Q3, Q4) ( to have the values of 3M, when selects YTD to have the values of 12M
If users selects months that are not in a quarter (Q1, Q2, Q3, Q4) (eg 29/2 - 31/3 - 28/4) maybe a blank value?
for one month selection is quite simple
IF(DISTINCTCOUNT('mytable'[date])=1;SUMX('mytable';'mytable'[Contacts unique clients]);"")Any ideas?
