Should be possible but the structure of your data is really important to answering how. Would you be able to attach a packaged workbook?
I have added the workbook with modified Superstore data
We do not have orderdate greater than 30th July 2018 in the example above
but i would like to stack the Fsales( forcasted sales) on thhe top of the incomplete month
Please hide unused feilds to to remove unwanted feilds
