YTD Help

Hello,

I have a column with Actual (CM) which is monthly and Actual (YTD) which is Year to Date.

I have another column named Fiscal Year and Posting Period (which is by month).

In this example, the month is working correectly since it is by month. (August "08")

However for YTD, it only works when I seclect 1 -8 in the Posting Period slicer.

Is there a way I can pick a Posting period to get it to work both ways?
