Dear Mr Greg_Deckler ,

here are the screenshots of my data (we are looking at row 276's total in Excel and the Rolling Average Sample 1 in Power BI). As you can see, the data does not match. Therefore, I would like to know if there are DAX amendments that I can make to ensure that this does not happen?

Further advice is much appreciated.

Yours sincerely,

Kaili
