Dax Measure -

Hi zameenakarmali 

Thank you for reaching out to the Microsoft Fabric Community Forum.

Regarding your query on creating DAX measure that dynamically evaluates premium values based on a selected month and the contract's start and end month numbers.

while I’m not fully aware of the exact structure of your dataset, I’ve created a sample .pbix file to demonstrate one possible solution.

Please try the below DAX:

Premium =

VAR Selected_Month_Number = SELECTEDVALUE(Dim_Date[Month No])

RETURN

CALCULATE (

    SUMX (

        'Data',

        SWITCH (

            TRUE(),

            'Data'[Ending Month Number] = 0, 'Data'[Gross Sales],

            'Data'[Starting Month Number] <= Selected_Month_Number

                && 'Data'[Ending Month Number] >= Selected_Month_Number, 'Data'[GBP Premium],

            0

        )

    ),

    REMOVEFILTERS(Dim_Date)

)

I’ve attached a few screenshots and the .pbix file demonstrating this logic. Please review them to see if this solution aligns with your requirements.

If this doesn’t fully meet your needs, could you kindly share a sample of your data and more detailed context? That would help us provide a more accurate solution.
