Help for finding error in Dax Formula

Siboska — Fri, 14 Oct 2022 08:48:28 GMT

Hi,

I have the following Dax Formula which is not returning the expected Result:

Dev. -1 month Benefits On Track KPI =

VAR _PreviousMonthBenefitsOnTrackKPI = CALCULATE(SUM(Initiatives[Benefits on track]), Initiatives[Snapshot type] = "End of month",HistoricalDatesInitiatives[Month relative today] = -1)

RETURN

IF(AND( _PreviousMonthBenefitsOnTrackKPI <> 1 || _PreviousMonthBenefitsOnTrackKPI <> 2 || _PreviousMonthBenefitsOnTrackKPI <> 3, [Current Benefits On Track KPI] = 1),1,

IF(AND( _PreviousMonthBenefitsOnTrackKPI <> 1 || _PreviousMonthBenefitsOnTrackKPI <> 2 || _PreviousMonthBenefitsOnTrackKPI <> 3, [Current Benefits On Track KPI] = 2 || [Current Benefits On Track KPI] = 3), -1,

_PreviousMonthBenefitsOnTrackKPI - [Current Benefits On Track KPI]))

The idea is I have 3 If statements.
The first states that if _PreviousMonthBenefitsOnTrackKPI Is NOTIN (1,2,3) AND [Current Benefits On Track KPI] = 1 THEN RETURN1 ELSE
IF _PreviousMonthBenefitsOnTrackKPI IS NOTIN (1,2,3) AND [Current Benefits On Track KPI] IS IN (1,2) THEN RETURN -1
ELSE

_PreviousMonthBenefitsOnTrackKPI - [Current Benefits On Track KPI]

The issue is that some of my projects Returns the second statement -1 which in reality should return the last statement.
I think the problem is related to how i'm nesting my IF's, AND's and OR's but can't fint the problem.

Hope someone can help

The 2nd if statement in your code is checking for current benefits being 2 or 3, but in your explanation you are checking for it to be 1 or 2. Try

Dev. -1 month Benefits On Track KPI = VAR _PreviousMonthBenefitsOnTrackKPI = CALCULATE ( SUM ( Initiatives[Benefits on track] ), Initiatives[Snapshot type] = "End of month", HistoricalDatesInitiatives[Month relative today] = -1 ) VAR _CurrentBenefitsOnTrackKPI = [Current Benefits On Track KPI] RETURN IF ( NOT ( _PreviousMonthBenefitsOnTrackKPI IN { 1, 2, 3 } ) && _CurrentBenefitsOnTrackKPI = 1, 1, IF ( NOT ( _PreviousMonthBenefitsOnTrackKPI IN { 1, 2, 3 } ) && _CurrentBenefitsOnTrackKPI IN { 1, 2 }, -1, _PreviousMonthBenefitsOnTrackKPI - _CurrentBenefitsOnTrackKPI ) )

Thx for the reply.
Made a mistake in my explanation. It should be 2 or 3.

Somehow when I changed my logic to Equal blank () or 0 it worked. Dunno if the <> operator was reading it the wrong way.
