Set analysis with 3 conditions

Hi there, 

I want to calculate the number of customers with an event name = 'P', the sum of total events >=2, and within the last 12 months.

I am using the following expression, but it does not return any value.

 

COUNT({<
[Customer ID] = {"=sum({< [Event Type]={'P'},Date={">=$(=date(addmonths(Max(Date),-12)))<=$(=date(Max(Date)))"}>}
                                      [Total Events])>=2"}
>}
distinct [Customer ID])

Could you please help.

use month and try

COUNT({<
[Customer ID] = {"=sum({< [Event Type]={'P'},Month={">=AddMonths(Max(Month),-12) <=Max(Month)"}>}
                                      [Total Events])>=2"}
>}
distinct [Customer ID])

First try to create flag in the script for sum(total events) >=2 and then call the flag in the set analysis

 

I hope already replied to your pervious thread

My script like this, If I create a flag as you suggested. I need to use group by and group by date, then that would not work.

LOAD
"Event Type",
"Customer ID",
"Date",
"Total Events"
FROM [lib://AttachedFiles/94cc618a-ac95-49f8-a660-3e2633e6e067.xlsx]
(ooxml, embedded labels, table is Sheet1);

besides I also need to use the total events column for other calculation.

From your above fact table drive your dimension table and link this table. in the dimension add your required fields as grp by

do you want to calculate the [Customer ID] who is having sum   [Total Events])>=2? if so 

then you link your fact table key -customer id with dimension table.

example:

load 

if(sum(total event >=2,'Y','N')

resident Table

group by customer ID

Yes but it would not work, I need to not only calculate that but also take into consideration the last 12 months.

Adding that script only gives me the customer who >=2 but in my expression, I also need to add a date filter.

Date={">=$(=date(addmonths(Max(Date),-12)))<=$(=date(Max(Date)))"}>}
 

I tried your suggestion by adding

test:
load

if(sum("Total Events" >=2),'Y','N') AS Flag,
"Customer ID",

Resident Events
Where [Event Type]='Login'
group by "Customer ID",

and then linked with my fact table :

COUNT({<
Date={">=$(=date(addmonths(Max(Date),-12),'YYYY-MM-DD'))<=$(=date(Max(Date),'YYYY-MM-DD'))"},
Flag={'Y'}
>} distinct[Customer ID])

 

it does not return correct result

pass 11 instead of 12

 

Date={">=$(=date(addmonths(Max(Date),-11),'YYYY-MM-DD'))<=$(=date(Max(Date),'YYYY-MM-DD'))"}
