Measure error to avoid blank pie chart "The function SUM cannot with values of type String"
I am creating a dashboard with various different pie charts that will be refreshed periodically throughout the year. I have one pie chart that currently has no data available and is therefore appearing as a blank space on my dashboard. People think there is an error with my dashboard, but there just hasn't been any of this type of spending yet. Eventutally, a pie chart will appear when that type of spending happens, but I'd like there to be a message to make it clear that this space is purposly blank at the moment.
I have followed instructions from various threads on here to create a measure using a card visual that should display "No data available" instead of a blank space. Every time I try to select the card I get "Error fetching data for this visual" "Calculation eorror in measure 'B-Base Planned'[Measure]: The function SUM cannot work with values of type string. "
The measure syntax I have used from exmaples in these forums is below:

Since you are trying to sum the blank data that function doesn't know what to do. You could take out the Sum function and it may work:
Measure = IF(ISBLANK('B-Base Planned'[Expense]), "No Data Available", "")Tried this and got a new error "A single value for column 'Planned' in table 'B-Base Planned' cannot be determined. This can happen when a measure formula refers to a colum that contains many values without specifying an aggregation such as min, max, count, or sum to get a single result."
*I did cahnge my formula to 'Planned' instead of 'Expense' , just realized I was using the wrong data field but still has the same issue*
This new error makes sence. I am trying to make a pie chart with each slice representing a different type of planned spending (e.g. office furnature, training, travel, etc.). I have 14 different spending types in my legend, which all currently sit at $0. I don't want any aggregation like SUM or COUNT, because the numbers I'm pulling from Excel are already totals. I just want there to be some indicator that there has been no spending, until a number is added to one of those rows in my Excel sheet.
Yep that makes sense. In that case you could also try this:
Measure = IF(ISBLANK(SelectedValue('B-Base Planned'[Expense])), "No Data Available", "")
