lost customers

powerbiexpert22 — Tue, 09 Jul 2024 17:07:53 GMT

the lost customers should show 0 it is showing 4 as below highlighted, i have created 3 measures to calculate lost customers.

lost customers are those customers who have not done any purcase last 2 months

please see sample pbix file:

Lost Customers Logic:

saleslast2months =

CALCULATE(Sales[salesamount],

DATESINPERIOD('Date'[Date],LASTDATE('Date'[Date]),-2,MONTH))

lostcustomer_flag =

IF(ISBLANK(Sales[saleslast2months]),"Lost",Sales[salesamount])

LostCustomers =

CALCULATE(

DISTINCTCOUNT(Customers[customer_id]),

FILTER(Customers,[lostcustomer_flag]="Lost"))

Hi powerbiexpert22

The output seems to be working as per the logic[No purchase in last 2 month], as of 12-01-2024 c1 has made a purchase while other 4 has not.

Can you explain the requirement a bit more elaborate?

Hi AnkitaaMishra , NaveenGandhi

Lost customers are those customers who placed orders before last 2 months from the specified date however they did not place any order within last two months from the specified date , below is the explanation based on the data

Date	Lost Customer Count	Reason
12-01-2024	0	There are no customers who placed any order before 12-Nov-2023
14-02-2024	0	There are no customers who placed any order before 14-Dec-2023
15-02-2024	0	There are no customers who placed any order before 15-Dec -2023
16-03-2024	0	There is 1 customer who placed orders before 16-Jan-2024 i.e C1 on 12th Jan 2024 but he placed another order on 14th Feb 2024 so he is not the lost customer
26-04-2024	2	There are 2 customers who placed orders before 26-Feb-2024 i.e. C1,C2 and they have not placed any order between 26-Feb-2024 and 26-Apr-2024 so these two are lost customers
28-04-2024	2	There are 2 customers who placed orders before 28-Feb-2024 i.e. C1,C2 and they have not placed any order between 28-Feb-2024 and 28-Apr-2024 so these two are lost customers
31-05-2024	3	There are 3 customers who placed orders before 31-Mar-2024 i.e. C1,C2,C3 and they have not placed any order between 31-Mar-2024 and 31-May-2024 so these three are lost customers

Look for lost column on sales table, you can neglect the summarize table
