Custom Column to Check if 2 consecutive months met a condition

beanboy — Wed, 26 Mar 2025 17:11:58 GMT

Hi Everyone,

I have a Customers table, and am looking for a way to add a flag column that flags if the Customer had 2 consecutive months of Calls that are greater than a target. The 'consecutive months' part is what is tripping me up.

I can do this the 'wrong' way of creating 12 variables, one for each Month, and doing a big series of checks:

IF ( M1 > Target && M2 > Target || M2 > Target && M3 > Target || etc..., "Flag" ) but I figure there's a better way.

I asked Copilot and got started, but again, I'm getting stuck on the consecutive months part of this.
First, for each row in the Customers table I am creating a temp table in memory that is storing the monthly Call volume for the trailing 12 months.

VAR __MonthlyTarget = 'Customers'[3 Month Target] / 3 VAR __EndDate = EOMONTH ( TODAY(), -1 ) VAR __StartDate = EOMONTH ( TODAY(), -13 ) VAR __Months = SUMMARIZE ( FILTER ( 'Calendar', 'Calendar'[Date] >= __StartDate && 'Calendar'[Date] <= __EndDate ), 'Calendar'[Month_Year], "Calls", [#Calls] )

Now, I need to check if this __Months temp table has 2 consecutive rows of Calls > __MonthlyTarget.

Copilot is telling me something along the lines of the below code.

VAR __ConsecMonthsExceed = SUMX ( FILTER ( __Months, [Calls] > __MonthlyTarget && CALCULATE ( SUM ( [Calls] ), FILTER ( __Months, [Month_Year] = EARLIER ( [Month_Year] ) +1 ) ) > __MonthlyTarget ), 1 ) RETURN IF ( __ConsecMonthExceeded > 0, "Flag" )

The Month_Year column is a date value (i.e. 1/1/2025, 2/1/2025, etc) so yes I am aware doing [Month_Year] + 1 probably isn't going up a whole month, but actually a day. This needs to be cleaned up, but isn't what I am stuck on. Im stuck on the 2nd check of the next month's Calls. Thanks for the help.

Thanks for responding.

Lets say I have a Customers Table like the following:

Customer ID	Customer Name	Month Target	2 Consecutive Months Flag
C001	Cust1	2
C002	Cust2	3

Customers table is related to the Calls fact table on the CustomerID field. There is one row in the table for each Call, and there can be multiple calls for a Customer on the same day

Call ID	Call Date	Customer ID
1001	1/1/2025	C001
1002	1/1/2025	C001
1003	1/1/2025	C001
1004	1/1/2025	C002
1005	1/2/2025	C001
1006	1/2/2025	C002
1007	2/1/2025	C001
1008	2/2/2025	C001
1009	2/2/2025	C001

I have an existing measure to count calls:

#Calls = COUNTROWS ( Calls )

Currently it is March 26th, so the trailing 12 months is Mar 2024 - Feb 2025.

I am looking to flag for each Customer if they had 2 consecutive months between Mar 2024 - Feb 2025 where the [#Calls] was greater than the Target.

In the example data above, Customer C001 had 4 calls in Jan2025 and 3 in Feb2025, and their target for each month was 2, so C001 did have 2 consecutive months exceeding the target.

Hi beanboy have done this using calculated columns, please try this

Calls Per Month =

VAR YearMonthKey = FORMAT(Calls[Call Date], "YYYYMM")

RETURN

CALCULATE(

COUNT(Calls[Call ID]),

FILTER(

Calls,

Calls[Customer ID] = EARLIER(Calls[Customer ID]) &&

FORMAT(Calls[Call Date], "YYYYMM") = YearMonthKey

)

Exceeded Target =

VAR Target = LOOKUPVALUE(Customers[Month Target], Customers[Customer ID], Calls[Customer ID])

RETURN IF(Calls[Calls Per Month] > Target, 1, 0)

Consecutive Exceeded Target =

VAR PreviousMonthExceeded =

CALCULATE(

MAX(Calls[Exceeded Target]),

FILTER(

Calls,

Calls[Customer ID] = EARLIER(Calls[Customer ID]) &&

(

(Calls[Year] = EARLIER(Calls[Year]) && Calls[Month] = EARLIER(Calls[Month]) - 1) ||

(Calls[Year] = EARLIER(Calls[Year]) - 1 && EARLIER(Calls[Month]) = 1 && Calls[Month] = 12)

)

RETURN

IF(Calls[Exceeded Target] = 1 && PreviousMonthExceeded = 1, 1, 0)

Hi beanboy,

Thank you for reaching out to Microsoft Fabric Community Forum.

I have taken sample data to reproduce your issue. Please test this query.

Call Month = MONTH(Calls[Call Date]) Call Year = YEAR(Calls[Call Date]) Two Consecutive Months Flag = VAR CallsByMonth = ADDCOLUMNS( SUMMARIZE( Calls, Calls[Customer ID], Calls[Call Year], Calls[Call Month] ), "Calls Count", COUNTROWS(Calls), "Target", LOOKUPVALUE(Customers[Month Target], Customers[Customer ID], Calls[Customer ID]) ) VAR ConsecutiveCheck = SUMX( CallsByMonth, VAR CurrentYear = Calls[Call Year] VAR CurrentMonth = Calls[Call Month] VAR CurrentMonthCalls = [Calls Count] VAR Target = [Target] VAR NextMonthCalls = CALCULATE( SUMX(CallsByMonth, [Calls Count]), FILTER( CallsByMonth, Calls[Customer ID] = EARLIER(Calls[Customer ID]) && Calls[Call Year] = CurrentYear && Calls[Call Month] = CurrentMonth + 1 ) ) RETURN IF(CurrentMonthCalls > Target && NextMonthCalls > Target, 1, 0) ) RETURN IF(ConsecutiveCheck > 0, "Yes", "No")

Here is the output:
