Hi I'm trying to solve for the following:
The screenshot below shows the two columns am trying to accumulate, Rows are the A1 Accounts dimension.

The next screenshot shows I have a column for Country and is list formatted with G2 Country. Now, if I am trying to sum for each country (e.g. US, Canada, UK etc.) couldn't I use the CUMULATE function with the following manner: CUMULATE(Exclude, FALSE, Country)? Exclude are the values I'm trying to sum while the FALSE omits the Boolean reset as recommended in the Technical documentation in this method and Country is the list formatted line item I'm trying to sum against. However, I'm getting an error as shown in the last screenshot below.

Screenshot showing the error message saying that Country is not a hierarchy. What am I doing wrong? Am I taking the right approach or there are other ways of solving for this? Your advice is much appreciated.

Kind regards,
Clarence
