Dynamic YoY percentage %

[erruiz]

Hello all,

I've searched mulitple posts on this forum to try to solve this problem and I have had no luck so far.

I want to be able to calculate a percentage change of different fiscal years based on the slicer selection. However, I keep getting this (Blank) error when I select different years. When the same year is selected, the value is 100%.

I edited the interactions on the slicers so that I can select multiple years referencing the same calendar (which is called 'xFY Calendar').

any help/suggestions would be appreciated.

Thank you!

Hey @erruiz, try this code, and if you encounter any issues, let me know.

YoY % = 
IF(
    ISBLANK([RiderSelectedYear]) || ISBLANK([RiderSelected2ndYear]),
    BLANK(),
    DIVIDE([RiderSelectedYear], [RiderSelected2ndYear], 0)
)

Hello @ahadkarimi, 

I'm still getting the same error. Let me know if you need me to share my dashboard.

Thank you,

Hi @erruiz, could you please check the RiderSelectedYear and RiderSelected2ndYear measures to see if they are correct?

for testing, you can add a table from the Visualization pane, include these two measures in the table, and review the values according to the slicer selections (are those correct?).

I suspect that the issue might be with the RiderSelectedYear and RiderSelected2ndYear measures. Could you verify and let me know if any problems still persist?

[erruiz]

Hello, I just checked and the measures don't show up on the table if both slicers are selected. Do you have an alternative solution to the RiderSelect measures? do you think I need to reference another data set since it appears that selecting two years from the same dataset cancels them out?

Hey @erruiz, make the following changes for the 2nd year:

RiderSelected2ndYear = 
VAR SelectedYearNumber = VALUE(RIGHT(SELECTEDVALUE('xFY Calender'[FY]), 2))
VAR PreviousYearNumber = SelectedYearNumber - 1
VAR PreviousFY = "FY" & FORMAT(PreviousYearNumber, "00")
RETURN
CALCULATE(
    [TotalRiders],
    FILTER(
        ALL('xFY Calender'[FY]),
        'xFY Calender'[FY] = PreviousFY
    )
)

if you would like to display a dash (-) instead of 'Blank' in the card, use the code below:

YoY % = 
IF(
    ISBLANK([RiderSelectedYear]) || ISBLANK([RiderSelected2ndYear]),
    "-",
    DIVIDE([RiderSelectedYear], [RiderSelected2ndYear], 0)
)

Please let me know what happend and if there are any issues.

Hello, this solution above works. I was hoping that the YoY% measure would be able to work by selecting any fiscal year instead of only the year prior but I suppose Power BI is limited in that way.

Thank you so much for your effort and your steady communication with me!
