Hi @Rob Rayborn ,
Thanks for your reply and sahring.
According to the screenshot you provided, I reproduced your issue on Excel 365.
Per my research, I found that this is a known issue in Excel. For more information, please refer to: Calculated field returns incorrect grand total in Excel.
Thanks for your understanding.
Per my testing, I think the following may be a workaround, please check if it is helpful.
Try to create a " - Revenue PY
" auxiliary column, and then create a new measure of " - Revenue PY + Revenue
".
Besides, if you have any suggestions about this issue, it is recommended that you go to File>Feedback in Excel to submit your suggestions to Microsoft directly.
Thanks.
Hope the information is helpful to you.
