Max date with conditions

[stewartad1]

Hi, 1st time poster here, hope this makes sense.

I need to retreive column "Current Risk Level" from table "RM_ImpactHistory" but with multiple conditions in place:
1. Find the max date but less than or equal to selectedDateTime, this is a variable coming from a slicer using selectedvalue

2. Risk ID being the same between these two tables: RM_ImpactAnalysisImpact and RM_ImpactHistory

Here is my current formula:

CurrRiskLevel =

MAXX(

    FILTER(RM_ImpactHistory,

    RM_ImpactHistory[RiskID] = RM_ImpactAnalysisImpact[RiskID] &&

    RM_ImpactHistory[RM_History.EventDate] <= [SelectedDateTime]

    ),

    RM_ImpactHistory[Current Risk Level]

)

Here's a picture of the report

Here's a picture of the corresponding data table

When 10/4/2024 4:23:33 PM is selected in the slicer, the expected result for "current risk level" should be "Medium: 12" and that is working. But when 11/6/2024 12:47:49 PM is selected in the slicer, the expected result for "current risk level" should be "Low: 8" and that is not working, it continues to show Medium: 12.

Here's a picture of the two options in the slicer

Hi @stewartad1 

Please try this:

CurrRiskLevel =
VAR _MaxDate =
    MAXX (
        FILTER (
            ALLSELECTED ( RM_ImpactHistory ),
            RM_ImpactHistory[RiskID] = RM_ImpactAnalysisImpact[RiskID]
                && RM_ImpactHistory[RM_History.EventDate] <= [SelectedDateTime]
        ),
        RM_ImpactHistory[RM_History.EventDate]
    )
RETURN
    CALCULATE (
        SELECTEDVALUE ( RM_ImpactHistory[Current Risk Level] ),
        FILTER (
            ALLSELECTED ( RM_ImpactHistory ),
            RM_ImpactHistory[RM_History.EventDate] = _MaxDate
        )
    )

Don't use aggregate functions to process text-type data, the result of the MAX(RM_ImpactHistory[Current Risk Level]) is Medium: 12 but Low: 8 because the initial M is in front of L.

Hope it can help,

Best Regards
