Datasource: Dataflow - SUM/Summarize dosen't work correctly

Hi together,

I don't know If the  headline is the right choise but let me explain:

First I create a Data Flow in Power BI Service to our NAV system. 

Then I load the Flow into Power BI Desktop Client (newest Version April 2019).

After that I try to summarize one column. (First I tried it with the little arrow on the site of the column name and after that I use SUM, nothing works)

But than I find out If I add for example to a table visual the original column (with "Don't summarize") and the Measure it works.


Have anyone a Idea why this can be happen?


Summe1 = Measure (SUM)

Betrag = Original Column

hi, @KBO 

It is strange, if the total value of table visual is still "0"? if the total of this column is 0 in dataset?

I know it's total weird, but you see I have in the original Column "Betrag" in every row a value. Only If I try to aggregate them with SUM for example he don't show me a value.

My Dataset based on the "New Connection" Data Flow - and in the Flow the Data is loaded correct :). If this was the question?
